“Advanced Packaging Solution for Heterogeneous Integration – Status and Challenges”

Currently higher computing power, high capacity and performance of memory are the major requirements of Al and GPU, accelerators and network devices. These demands lead to the adoption of the advanced packaging technologies to increase bandwidth density, thermal performance and to improve electrical performance with shorter interconnection length. High-performance chip size continues to increase up over one reticle size and the cost of the leading-edge silicon node is recently soaring. So various chiplet packaging solutions, such as 2D, 2.5D and 3D have been introduced. Among these solutions, the highest density and speed can be obtained with 3D IC packaging technology. Stacked 3D ICs contain multiple dies stacked, aligned, and bonded in a single package, using through-silicon vias (TSVs) and hybrid bonding techniques for inter-die communication. In this presentation, the above mentioned advanced package solutions are to be introduced as well as the status and challenges in terms of process development in stacked 3D IC packaging.

Un-Byoung Kang received the Ph.D. degree in material science and engineering from the Hanyang University, Seoul, South Korea, in 2004. He joined Samsung Electronics, Kiheung, South Korea, in 2004, where he was involved in the semiconductor packaging process development like bumping, Cu RDL, TSV via last, wafer supporting system, and 3D chip bonding as well as the package product development such as WLP, CIS-CSP, 3D TSV-SIP, EDP-TSV, and HBM. He is currently a Master (VP of Technology) in advanced packaging process development team.

“An Overview of the Past, Present and Future of 3D Device Technology”

In 1965, Moore’s Law, which states that the number of transistors in an integrated silicon circuit doubles about every two years, has been slowed due to the limitation of the interconnect pitch scaling. Therefore, many IDM companies are currently focusing on the development of micro-processes that reduce the chip size by developing new process integration such as multilayer or 3D structure device technology. However, due to the large process cost of the FEOL process development to achieve the above-described goals, significant efforts are being made to open the era of “Beyond the Moore” with the development of backend & package process technology. In this presentation, the past, present and future of 3D stacking technology that can respond to the 4th industrial revolution era and overcome structural limitations for semiconductor integration will be discussed.

Dr. Jiho Kang is the Fellow in the R&D Division of SK Hynix, Korea and currently leading WF Bonding PJT in the R&D Process.

Dr. Kang first joined Intel Corporation in Hillsboro, Oregon in 2006 and worked as a senior etch process engineer. From 2012, he participated in the development of Intel TSV process technology, which became the basis of Intel FoverosTM Technology. From 2016, he worked as a group leader, responsible for BEOL process development for Intel 14, 10 & 7nm technology nodes.

Dr. Kang received Ph.D. in Materials Science and Engineering from The Ohio State University, Columbus, Ohio. Previously, he earned B.S. in the Metallurgical Engineering from Yonsei University and M.S. degree in Materials Science and Engineering from KAIST in Korea.

“SiP, The Next Revolution for Microelectronics Packaging and The Challenges”

The entire microelectronics packaging industry has been driven by consumer market harder and harder over the last 10 years for providing smaller footprint and thinner product solutions. Now the entire industry is approaching the critical barrier breaking point to continue the miniaturization trend for the next 10 years and the only major solution to the challenge is SiP packaging technology. In this presentation, some of the major SiP manufacturing technical challenges and solutions will be discussed to provide value add reference for our audience.

“Glass Interposer Integration of Logic and Memory Chiplets: PPA and Reliability Benefits”

Glass interposer offers low-cost options to embed chiplets directly inside the substrate itself. This enables 3D stacking configuration between the embedded dies and the conventional flip-chip dies mounted directly on top. Furthermore, the interconnect pitch and through-glass-via (TGV) diameter in glass are becoming comparable to their counterparts in silicon. In this work, we investigate the power, performance, area (PPA), signal integrity (SI), and power integrity (PI) benefits of 3D stacking enabled by glass interposer in comparison with silicon interposer. Our research is based on chiplet/package co-design, where our design start is a register transfer level (RTL) description of RISC-V architecture for the chiplets. Our final design reaches graphic data system (GDS) layouts of the chiplets and their routing in interposers. Our experiments show that the 3D glass design is 2.58X smaller than the 2.5D, and 1.36X smaller than the 2D design. Our glass interposer shows 20.8X shorter wirelength, 10X smaller PDN DC impedance, and 9.7% faster settling time for switching voltage compared with silicon. Lastly, the eye opening in glass is 15% larger than silicon.
