Summary: While Silicon has scaled aggressively by over a factor of a few thousand over the last six decades the progress in packaging has been more modest — a linear factor 4-5 in most cases. In this talk, we will examine the reasons for this lag and what we are doing to fix this imbalance. Packaging is undergoing a renaissance where chip-to-chip interconnects can approach the densities of on-chip interconnects. We will discuss the technologies that are making this happen and how these can change our thinking on architecture and future manufacturing. Specifically, we will discuss two embodiments: Silicon as the next generation packaging substrate, and flexible electronics using fan-out wafer level processing. Finally, we’ll discuss how these developments can help put some intelligence into Artificial Intelligence and bring about changes in Medical Engineering.

Summary: This presentation will discuss high-density multi-die integration approaches both in 2.5D and 3D, though we will emphasize 2.5D architectures. Specifically, we first discuss various 2.5D approaching including Heterogeneous Interconnect Stitching Technology (HIST), which enables the interconnection of multiple dice of various functionalities in a manner that mimics monolithic-like performance, yet utilizes advanced off-chip interconnects and packaging to provide flexibility in IC fabrication and design, improved scalability, reduced development time, and reduced cost. A key feature of HIST is the ability to place a ‘stitch chip’ between adjacent ICs on the surface of an organic/ceramic package and use multi-height I/Os to interface the active dice to the package and stitch chips simultaneously. Design considerations and benchmarking (power delivery, signaling, and thermal) will be described and experimental demonstrations will be shown. Secondly, we discuss highly-scaled 3D ICs using sub-micron TSVs and report fabrication and characterization results; we also discuss the impact of TSV geometry on 3D end-to-end interconnect links (energy and latency) accounting on-chip wire resistance and capacitance. Third, and lastly, we briefly discuss 3D IC applications in CMOS multimodal biosensors.

Summary: Why did Silicon Valley come into being? The story goes back to the local hobby group of Hams (amateur radio operators) trying to break RCA’s tube patents, early Stanford engineers, the sinking of the Titanic and WW I, early “angel” investments, Fred Terman and Stanford University, local invention of high-power tubes (gammatron, klystron), WW II and radar, William Shockley’s mother living in Palo Alto, new approaches to running companies, and the SF Bay Area infrastructure that developed — these factors pretty much determined that the semiconductor and IC industries would be located in the Santa Clara Valley of California, and it would become the model for innovation worldwide. And since semiconductor device development and production were centered here, it made sense that Charles “Bud” Eldon of H-P would be asked by his management to start an IRE Group on Product Engineering in Palo Alto, to serve our local engineers (which grew into today’s EPS Society). Bud went on to become president of the IEEE.
Discover the exciting and colorful history of technology development and innovation that began in Palo Alto CA in 1910 and spread across the Santa Clara Valley. You’ll meet some of the colorful characters – Cyril Elwell, Lee De Forest, Bill Eitel, Charles Litton, Fred Terman, David Packard and others – who set leadership patterns for the electronics industries through their inventions and process development. You’ll find out about Charles “Bud” Eldon of HP, who founded a predecessor IRE Group in 1954 that become CPMT, now EPS, and served as president of the IEEE. Find out why Silicon Valley has had such an effect on the world.

Bio: Paul Wesling got interested in technology as a youngster. He went on to receive his BS in electrical engineering and his MS in materials science from Stanford University. Following assignments at GTE/Lenkurt Electric, ISS/Sperry-Univac, Datapoint Peripheral Products (VP – Product Integrity), and Amdahl (mainframe testing), he joined Tandem Computers in Cupertino (now part of Hewlett Packard) in 1985. He designed several multi-chip module prototypes, managed Tandem’s Distinguished Lectures series, and organized a number of advanced technology courses for his Division and also for the IEEE. He managed a grant from the National Science Foundation for the development of multimedia educational modules. Paul retired from HP in 2001, and then served for 10 years as the Communications Director for the IEEE’s S.F. Bay Area Council.

As Vice President of Publications from 1985 through 2008, he supervised four archival journals and a newsletter for IEEE’s Electronics Packaging Society. In this assignment he generated over $4 million in incremental revenue, for new Society programs and reserves. He is a Fellow of the IEEE, and received the IEEE Centennial Medal, the Board’s Distinguished Service award, the Society Contribution Award, and the IEEE’s Third Millennium Medal. He has organized over 500 courses for the local IEEE chapter in the Santa Clara Valley (Silicon Valley), many of them held at Stanford University (and, more recently, at Silicon Valley company facilities).

3D Printing in Electronics Packaging: Hype, Hope, or Happening? 🗓

— design tools, materials, 3D-printing processes, micro-assembly systems, deposit, cure, embedded components …

Speakers: Dr. Chris Bailey, University of Greenwich, and Dr. Jie Xue, Cisco
Meeting Date: Tuesday September 19, 2017

Summary: 3D-Printing (or Additive Manufacturing) has received significant media attention during the last five years. In 2012 the Economist published an article on this technology which stated that it will lead to a 3rd industrial revolution. A number of companies are now commercializing materials, design/software and 3D-Printers, and these are being used in a number of manufacturing sectors including aerospace, medical, and construction and consumer products. In China alone the 3D-Printer market is expected to be worth over 10Bn RMB by 2018, and the Government has recently initiated a policy to provide every school with 3D-printing capabilities.
But what impact will 3D-printing have on the electronics packaging and manufacturing community? Will 3D-Printing be just hype, or is there hope that these technologies will impact the way we manufacture and package electronic systems — or are developments already being commercialized? Will 3D-Printing of electronic circuits or components be the next phase of the additive manufacturing revolution? This presentation will discuss the challenges for design tools, materials, and 3D-printing processes in the context of electronics manufacturing/packaging. In particular, printing and micro-assembly systems are required that can accurately deposit and cure both functional and structural materials and place/embed components in an integrated manner within a single platform. The performance and electrical behavour of printed conductive materials is also a challenge as they must meet the performance of materials currently used. And of course the overall quality and reliability of 3D-printed electronic systems must meet industry requirements. This presentation will detail the current status of 3D-printing for the manufacture of electronic systems, and provide some insights on how it may impact our community in the future.

Probabilistic Design for Reliability in Electronics and Photonics 🗓

— accelerated testing, stressors, vulnerable elements, sensitivity analyses, predictive modeling, robustness, assured levels …

Speaker: Ephraim Suhir, Ph.D.
Webinar Date: Wednesday, July 19, 2017
Time: 8 AM PDT (11:00 AM EDT)
Cost: none (open only to CPMT members)
Location: on the Internet

Summary: The recently suggested probabilistic design for reliability (PDfR) concept in electronics and photonics (EP) is based on 1) highly focused and highly cost-effective failure-oriented accelerated testing (FOAT), aimed at understanding the physics of the anticipated failures, and at quantifying, on the probabilistic basis, the outcome of FOAT conducted for the most vulnerable element(s) of the product of interest for its most likely applications and the most meaningful combination of possible stressors (stimuli); 2) simple and physically meaningful predictive modeling (PM), both analytical and computer-aided, aimed at bridging the gap between the FOAT data and the most likely operation conditions; and 3) subsequent FOAT-and-PM-based sensitivity analyses (SA) using the methodologies and algorithms developed as by-products at the two previous steps. The PDfR concept proceeds from the recognition that nothing is perfect and that the difference between a highly reliable and an insufficiently reliable product is “merely” in the level of the probability of its failure. If this probability, evaluated for the anticipated loading conditions and the given time in operation, is not acceptable, SA can be effectively employed to determine what could/should be changed to improve the situation. The PDfR analysis enables one also to check if the product is not over-engineered, i.e., is not superfluously robust. If it is, it might be too costly. The operational reliability cannot be low, but it does not have to be higher than necessary either. It has to be adequate for the given product and application. When reliability and cost-effectiveness are imperative, ability to optimize reliability is a must, and no optimization is possible if reliability is not quantified. It is shown also that the optimization of the total cost associated with creating a product with an adequate (high enough) reliability and acceptable (low enough) cost can be interpreted in terms of the adequate level of the availability criterion. The major PDfR concepts are illustrated by practical examples. We elaborate on the roles and interaction of analytical (mathematical) and computer-aided (simulation) modeling. It is shown also how the recently suggested powerful and flexible Boltzmann-Arrhenius-Zhurkov (BAZ) model and particularly its multi-parametric extension could be successfully employed to predict, quantify and assure operational reliability. The model can be effectively used to analyze and design EP products with the predicted, quantified, assured, and, if appropriate and cost-effective, even maintained and specified probability of operational failure. It is concluded that these concepts and methodologies can be accepted as an effective means for the evaluation of the operational reliability of EP materials and products, and that the next generation of qualification testing (QT) specifications and practices for such products could be viewed and conducted as a quasi-FOAT that adequately replicates the initial non-destructive segment of the previously conducted comprehensive full-scale FOAT.

Summary: Additive manufacturing (AM), commonly referred to as 3D printing, is a booming technology (or, better, a set of technologies) in a number of application areas, including architecture, automotive, aerospace, biotech, electronics, fashion and food to name just a few. AM actually encompasses a broad array of processes aimed to directly synthesize a 3D object from raw materials, using a layer-by-layer deposition or growth sequence under computer control.
In the electronic market, and specifically in the RF and Microwave field, from expensive satellite communication systems to high volume microwave electronics, AM has the potential to change the way systems are designed, integrated and operated and is therefore considered a strategic technology and a key enabler for accelerated engineering processes, highly efficient products and new agile supply chains. Totally new design approaches that will improve performance, make mass optimization practical, allow the miniaturization of complex systems and dramatically reduce the design/manufacturing/assembly cycle costs are possible with AM. Along with these attributes AM provides an environmentally-friendly alternative to conventional manufacturing.
This webinar will present a review of the current state of practice in additive manufacturing for RF/microwave applications including those areas where much remains to be done.

Summary: Electronics is ubiquitous in today’s world. Semiconductors provide the computing power and data conversion. Power sources, typically batteries, on small, uncorded devices are challenging for long operation. Heat generation, i.e., power loss, is a significant concern. The packaging is designed to survive both the anticipated environmental extremes and the application handling. The system is held together via a substrate that connects the various elements of the application into a functional circuit. Millimeter sized “pills” with video capability have been designed and applied in medical applications. As the size of the “systems” continues to shrink into the micron range, the question that arises is “How can we design a system that can perform its mission and still be manufactured in quantity?” This presentation addresses some of the potential issues that need to be resolved in order to be successful. One critical fact is that the manufacturing processes do not exist today. They need to be invented. The intent of this paper is to initiate dialogue and research/development to accomplish the manufacture of micron-sized systems.
