Increasing demands on requirements for high power microwave and mm-wave communications systems need volume compaction but also require a high degree of heat transfer to meet system needs. In many cases, this precludes use of emerging commercial embedded die approaches to volume compaction. Also, complex, low volume, and high value added microwave systems often require repair and replace reworkability at the die level. The Raytheon U-Mass/Lowell (UML) Research Institute (RURI) has developed and demonstrated integration of a three dimensional printed near chip scale interposer. This capability enables die embedment that can accommodate die level reworkability and direct cold plate access for the device. Realization of the interposer includes an nFD print of a 3D insulating structure, a planarizing dielectric, a multi-axes conductor print, a printed gasket and a conformal conductor print over multiple materials at multiple heights to make the final interconnect. This structure is embedded within a PCB assembly leading to circuit card assemblies (CCAs) that can then be stacked for volume efficiency. Robustness to multiple surface mount reflow profiles and thermal cycling will be shared. The developed approach can be used and extended to add functionality beyond the basic interconnect. Details of the fabrication and integration of the interposer will be provided.

Semiconductor scaling to smaller dimensions has led to tremendous improvement in electronic systems performance. Computer systems that used to occupy several rooms are now available in the palm of your hand. However, as semiconductor scaling saturates, other paradigms are necessary for improving the systems performance. One such paradigm of performance improvement is advanced packaging of heterogeneous chips from different semiconductor nodes, different construction and different sources - often called heterogeneous integration (HI). HI is necessary because system performance is required to grow 1000x over the next 7-10 years, especially for Artificial Intelligence (AI) applications. A subset of AI, called machine learning, relies of artificial neural networks that simulate a human brain. In this talk, we compare and contrast the different HI packaging options which include conventional 2D single-chip and multi-chip packages with high-density laminates, package-on-package (PoP) configurations, 2.5D silicon interposers, silicon bridge packages, and fully 3D stacked packages. Many of these configurations are being developed in the IBM AI Hardware Research Center (AIRC). We then elaborate on the Direct Bonded Heterogeneous Integration Si-bridge packaging scheme.

Bio: Kamal Sikka is a Senior Technical Staff Member at IBM. He joined IBM after obtaining his PhD degree in Mechanical Engineering with a focus in Thermal Sciences from Cornell University. His initial work at IBM focused on thermal solution development, e.g., thin-gap thermal paste technology, for IBM OEM customers such as Compaq/HP. This was followed by IBM server thermal solution development such as an Adhesive Thermal Interface coupled to SiC and Diamond heat spreaders.

Kamal then took on the management of the IBM Packaging Development Thermal Development and Modeling department. He transformed the Advanced Thermal Lab with introduction of multiple automated thermal chip-package testers and initiated the Mechanical Analysis Lab as the package substrate technology transitioned from ceramic to organic laminate materials. His team delivered multiple advanced thermal solutions for IBM Systems such as advanced TIMs, diamond heat spreaders, dual heat spreaders and package integrated heat sinks. He was also the leader of the thermal qualification teams for IBM's ASIC menu packages from Cu08, Cu65, Cu45, Cu32, and FX-14 technologies. Besides developing thermal solutions, Kamal led the IBM package modeling and simulation teams, developing modeling protocols for IBM's laminate package technology. Kamal also led task forces for resolving the Microsoft Xbox issues on a consultancy basis, and solder interconnect delamination in workload simulator systems.

Subsequently Kamal served in the senior manager role for the Packaging Development team with Unit Process responsibilities spanning from C4, CPI, laminate, Bond & Assembly and thermal development. Under his leadership, the team reduced the C4 pitch for IBM server packages, co-developed an advanced TIM with an industrial partner, and conducted fundamental research on glass interposers.

Kamal then transitioned from IBM Systems to IBM Research initiating the Heterogeneous Integration (HI) effort and defining the HI strategy. He has led the establishment of the HI Lab at Albany NY. The HI lab integrates material characterization, thermal analysis, mechanical analysis, Bond & Assembly, and reliability equipment in one location. He is also the technical leader for IBM Direct Bonded Heterogeneous Integration (DBHi) Si-bridge and stacked Si-microcooler technologies.

There is great need for multi-die packaging – Chipletes & SiP – to meet the needs of High Performance Computing for Data Ceteers, 5G, Accelerators, AI & ML, & Autonomous Driving applicatiopns and more. A good example of the package type used in such high-performance computing product mass production is Silicon Interposer IC package with ultra-high density I/O, for high performance GPU, and high-speed networking devices, Between the ASIC chip and the HBM stack, a lot of high-speed signal lines and thousands of small vias are connected. In addition the silicon interposer has an important structure-TSV (Through Silicon Via) to act as the connection between the ASIC chips or the HBM chips and the package substrate. Considering productivity and cost, there is great need to develop an advanced packaging solution to fill in the “Gap” between Flip Chip BGA based high density build up substrate and silicon Inteerposer with TSV. One such solution would be high density Fan-Out based upon the well known and well established robust Wafter Level Fanout process and manufacturing infrastructure.

In this paper, we report on an internally developed semiconductor package design flow and platform is proposed for FOCoS package. The platform integrates with semiconductor package design solution and integrated circuit (IC) design solution. It can balance the developing schedule and cost in the design stage of FOCoS. The design flow of FOCoS includes physical design, design rule check (DRC), layout versus schematic (LVS) check and full wave electromagnetic (EM) analysis. In physical design, the major design platform is still based on conventional package design solution like Cadence Allegro APD+ or Mentor XPD. But, to speed up design cycle time, the auto-router for FOCoS RDL design is used in IC design solution. A self-developing program linking to conventional package design solution and IC design solution is applied on the two different file format transferred. Therefore, the FOCoS RDL designer can utility the auto-router to complete the preliminary design, then transfer the design file to conventional package design platform for modification. Once the design is completed, the DRC and LVS can confirm the correctness in rules and interconnection. The difference with IC design flow, it utilizes package netlist to do LVS check in this platform, not schematics. Hence, it easily uses the program of LVS to do 3D IC check. In addition, the location of DRC error can be imported to conventional package design platform and the designer can fast fix the error in conventional package design platform. Finally, the full wave 3D solver extracts the S-parameter of die-to-die or die-to-HBM interconnection for electrical analysis. A real case using the design flow is demonstrated with design cycle time reduction. This design flow is integrated in the package & assembly PDK for HD Fanout package. We shall incorporate AI & ML tools to futher optimize the design process in the future.

This talk will discuss efforts to additively pattern and utilize liquid metals as conductive inks for stretchable, soft, and reconfigurable electronics1. Alloys of gallium have metallic conductivity, yet have low viscosity, low toxicity, and negligible volatility. Despite the large surface tension of the metal, it can be patterned into non-spherical 2D and 3D shapes due to the presence of an ultra-thin oxide skin that forms on its surface, as shown in the image.

Liquid metal is extremely soft and flows in response to stress to retain electrical continuity under extreme deformation. By embedding the metal into elastomeric or gel substrates, it is possible to form soft electrodes, stretchable antennas, and ultra-stretchable wires that maintain metallic conductivity up to ~800% strain. The resulting conductors are self-healing. The metals can also be filled into microchannels or hollow fibers for capacitive touch sensors, and mechanically tough fibers. It is also possible to 3D print the metal for source and drain contacts for transistors and as interconnects for energy harvesters. More recently, we demonstrated that liquid metal circuits can also be used for soft, tactile logic2.

Perhaps one of the more unique aspects of liquid metals is the ability to manipulate their shape for reconfigurable electronics. Electrochemistry can deposit and remove the oxide layer to manipulate the interfacial tension—a dominante force at the microscale—over an enormous range. Reductive potentials remove the oxide layer and put the metal in a state of high tension. However, oxidative potentials deposit the oxide layer on the metal and put it in a state of low tension. Experiments suggest the tension could be near zero using less than one volt. Unlike electrowetting, which can require hundreds of volts, here, the changes result due to electrochemically deposited species on the metal surface.

Neuromorphic and AI computing hardware is trending away from traditional von Neumann computational architectures. This transition is opening the door to a wide range of novel devices and integration solutions. Over the past 10 years, my research group has focused on fabrication and integration strategies for CMOS-compatible, non-volatile, analog memory devices (aka: memristors). These memristive devices have the potential to act as neuronal synapses in neural networks, but can also function as tunable elements in array-based accelerators. Introducing unique materials and novel memristive devices into the traditional CMOS fabrication process presents many challenges, from both the process integration and packaging standpoint. In this presentation I will discuss integration strategies that we have used to develop novel hardware solutions.

Superconducting electronics and quantum systems are experiencing a significant growth in interest due to recent successes in superconducting quantum computing. Cryogenic electronics systems present a unique set of challenges for complex, densely integrated systems with large numbers of components and cables/interconnects often spanning multiple temperature stages. Conventional microwave co-axial cables that are currently in common use can stress volume and thermal constraints of these systems. Suitable connectors for such systems are also needed. In this presentation, I will describe our R&D efforts on high performance, multi-conductor superconducting flexible cables and connectors made using thin-film and wafer-level fabrication approaches. These interconnects have high microwave performance to multiple 10’s of GHz, low mass, and low thermal cross-section structures. This hardware shows great promise as interconnect structures for future superconducting and cryogenic electronics systems, including superconducting microwave quantum computing applications.

This presentation will explore the use of on-demand liquid metal droplet jetting to fabricate printed circuit patterns. Through proper control of drop size, jetting frequency, and drop spacing, solid metal traces whose conductivities match that of the bulk metal have been fabricated on temperature sensitive flexible polymer substrates. The process uses inexpensive wire, rather than nanoparticle ink, as the feedstock material. Pre and post-processing steps normally used with nanoparticle ink processes, such as substrate cleaning and ink drying + curing, are eliminated. The presentation will include examples of non-planar printing as well as 3D printed features without the need for support structures.

The DARPA Microsystems Technology Office (MTO) Electronics Resurgence Initiative (ERI), initially announced in 2017, is a response to several technical and economic trends in the microelectronics sector. Among these trends, the rapid increase in the cost and complexity of advanced microelectronics design and manufacture is challenging a half-century of progress under Moore's Law, prompting a need for alternative approaches to traditional transistor scaling. Meanwhile, non-market foreign forces are working to shift the electronics innovation engine overseas and cost-driven foundry consolidation has limited Department of Defense (DoD) access to leading-edge electronics, challenging U.S. economic and security advantages. Moreover, highly publicized challenges to the nation's digital backbone are fostering a new appreciation for electronics security-a longtime defense concern.

ERI ensures far-reaching improvements in electronics performance well beyond the limits of traditional scaling. The programs make a significant investment to create a more specialized, secure, and automated electronics industry that serves the needs of both defense as well as the domestic commercial sectors. Building on the tradition of other successful government-industry partnerships, ERI aims to forge forward-looking collaborations among the commercial electronics community, defense industrial base, university researchers, and the DoD to address these challenges. Given today's cost, complexity, and security challenges, the nation now stands ready to collaboratively innovate the next wave of electronics progress.

Leveraging 3D heterogeneous integration, the next wave should support continuing electronics progress despite challenges to traditional silicon scaling. This integration will enable innovators to both add new materials and devices to the silicon foundation and create specialized functions precisely designed to meet the diverse needs of the commercial and defense sectors. To manage the complexity of working in three dimensions, the next wave will also demand new architectures and design tools that address rising design costs, enable rapid system upgrades, and make security integration a primary design concern.

Silicon integrated photonics has grown in the last decade to fill the market with classical devices that offer tremendous SWaP benefits over conventional bulk optics or fiber components. For quantum systems the material and device losses present were still too large to allow for larger scaling of systems at the single and low photon level. Over the last couple years, both industry and government laboratories have worked closely with commercial foundries to drop the optical losses to levels that now can scale quantum systems. This research area, the results, and the next steps forward for integrating other materials and qubit systems into the platform will be the subject of my talk.

This presentation will provide an overview of DoD Executive Agent (EA) efforts promoting printed circuit board and interconnect technology (PrCB) development projects leveraging domestically sourced materials and processes to address the most advanced circuit board and microelectronics packaging requirements. The presentation will also offer insights into related DoD policy and guidance development efforts designed to promote the acquisition and sustainment of electronic systems required to provide US Warfighters with unrivaled electronic systems.

Today's military systems rely heavily on electronics to complete their intended missions, and Interconnect Technologies are a critical and integral part of those electronics. Over the last 40 years the U.S. printed circuit board manufacturing industry has steadily declined, as an increasing number of facilities closed, merged with other companies, or moved offshore. This has exposed the Department to vulnerabilities accessing critical Interconnect Technology products. Additionally, recent and ongoing Covid-19 pandemic impacts have exacerbated and highlighted supply chain impacts that further exposed vulnerabilities within this industry sector.

DoD has become reliant on foreign, and sometimes undependable suppliers to deliver advanced technology products. The DoD PrCB EA, via DoD Directive 5101.18E, was chartered to facilitate access to reliable, trusted, and affordable products and technologies that meet the quality, performance, and security requirements of the DoD. The EA is facilitating collaboration within and across the DoD to conduct research, development, and sustainment efforts targeting component-unique requirements.

This presentation will update the audience on DoD Executive Agent progress towards achieving it’s mission to ensure DoD access to trusted and affordable electronic interconnect technologies necessary for critical national defense systems and warfighter superiority.

Each year, more than 60% of Cu is used in electrical applications due to its excellent electronic, thermal and mechanical properties. Here, we report the printable Cu ink material development for flexible conformal electronics, particularly high temperature applications. We demonstrate radio-frequency antennas through all-printed Cu features on flexible ceramic material, in which we achieve a reflection coefficient of - 60 dB at the resonant frequency of 2.5 GHz. In addition, all high-temperature electronics printed onto flexible ceramics also exhibit high sensitivity (0.05% °C−1) and accuracy (1 °C) for temperature sensing between 25°C and 600°C, satisfying the real-time high-temperature monitoring. Our findings show that Cu conductors printed onto flexible ceramics offer an opportunity to develop conformal high-temperature electronics with hybrid eco-friendly printability, providing new routes for manufacturing large-scale flexible hybrid electronics. In addition, flexible dielectric material with high thermal conductivity will also be discussed.

Smart textiles have been a research topic for more than 20 years. A broad range of technologies has been developed and investigated. The solutions range from conductive or otherwise functionalized yarns to integration technologies for conventional and hybrid electronics including sensors. The maturity and scalability of these technologies have been major challenge on the way to bring the research results into the market, considering that two very different industries have to join efforts for success. Better understanding of the different technological approaches and their limitations together with the development of corresponding equipment can enable the transfer to industry. Regarding the applications, research still focuses on medical applications in the areas of prophylaxis, diagnosis, monitoring, treatment and rehabilitation. These devices are typically very specialized and optimized for different locations on the body. This specialization of the devices leads to new requirements regarding the materials, integration technologies and reliability. At the same time, it is necessary to develop and verify systems in short cycles. With modular electronic systems and textile bus structures these requirements can be met.

Disposable wireless sensor networks (WSNs) will allow every corner of the world to be connected through the Internet of Disposable Things (IoDT). This novel technique, constructed in a small, compact, disposable package at a low price point, can connect functional things inexpensively for only a programmed period and then be readily thrown away. The IoDT devices will provide a great degree of intelligence and autonomy by enabling rapid deployment of new types of IoT applications and the creation of new services at an affordable price point. Despite excitement about this conceptual paradigm for WSNs, the IoDT has not been widely explored because of requirements for substantial technological advances in independent and self-sustainable function, and the multidisciplinary nature of application-dependent WSNs. In particular, low-cost and eco-friendly IoDT devices are critical to providing disposable and biodegradable functionality as the devices are expected to be increasingly pervasive and fast updated for their rapid deployment. Paper has recently emerged as a flexible and low-cost game-changing substrate for next-generation electronics, known as papertronics, because of its excellent mechanical and dielectric properties with chemical and thermal stability. The biodegradability of papertronics has attracted much attention as the future of green electronics, reducing the dramatic increase in electronic waste. Integrated papertronics will have the transformative potential to yield exceptionally powerful functions and performances for many IoDT applications such as monitoring public health and surveilling environmental conditions. In this talk, he will present many innovative papertronic devices that his research group recently developed including paper-based PCBs, paper-based microfluidics, and paper-based batteries. Details of the frontier of research to improve the performance of the papertronics will be discussed, followed by a critical perspective on strategic future directions.

Chronic diseases require a continuing medical care and limits the daily activities of patients. Digital health solutions, such as wearable electronics, enable transition from discrete monitoring to continuous monitoring. However, current body-worn sensors and wearable electronic devices are based on miniaturized form of conventional rigid electronics, which leads to bulky and uncomfortable devices and will prevent the further adoption of the technology. The circuit board of the system defines the size, shape, and form factor of the unit, leading typically bulky and clumsy wearable systems. Unlike traditional electronics, printed intelligence enables fabrication of devices that are thin, flexible, and stretchable.

As an example, we have demonstrated touch, temperature, pressure, ECG sensors and systems. Sensor elements are fabricated on soft and stretchable substrates using inkjet and screen-printing technologies. In addition, pre-amplifiers can be fabricated by printing using organic semiconductors. The performance of printed amplifiers is limited to low-frequencies, and therefore, Flexible Hybrid Electronics approach is used when computation power or high-frequency communication is needed. Reliability of stretchable-rigid interface is one of the key challenges in such cases. This presentation will focus on fabrication of printed conformable body-worn sensors and sensing systems including discussion related to rigid-stretchable interface.
