IEDM: Backside Power Delivery
By Paul McLellan - 09 Mar, 2023 - Comments: 0

One part of the short course that I attended at IEDM in December was about backside power delivery networks. It was presented by Gaspard Hiblot of imec and titled "Process Architectures Changes to Improve Power Delivery." The presentation is co-credited with Geert Hellings and Julien Ryckaert. I should preface this post with the fact that this presentation was 80 slides long and so I will only... » read more

Heterogeneous IC Packaging: Optimizing Performance And Cost
By Mike Kelly - 18 Aug, 2022 - Comments: 0

Leading integrated circuit (IC) foundries are already shipping 7-nm and 5-nm wafers and 3-nm product qualifications are ongoing. Wafer costs continue to soar as high transistor density requires ever more expensive processes to fabricate them. Even if defect densities can remain relatively flat as new nodes emerge, the cost per unit area of silicon increases nonlinearly. These economics have pla... » read more

A Review on the Fabrication and Reliability of Three-Dimensional Integration Technologies for Microelectronic Packaging: Through-Si-via and Solder Bumping Process
By Technical Paper Link - 23 Dec, 2021 - Comments: 0

Abstract "With the continuous miniaturization of electronic devices and the upcoming new technologies such as Artificial Intelligence (AI), Internet of Things (IoT), fifth-generation cellular networks (5G), etc., the electronics industry is achieving high-speed, high-performance, and high-density electronic packaging. Three-dimensional (3D) Si-chip stacking using through-Si-via (TSV) and sol... » read more

Heterogeneous Integration Using Organic Interposer Technology
By Amkor - 17 Nov, 2021 - Comments: 0

As the costs of advanced node silicon have risen sharply with the 7 and 5-nanometer nodes, advanced packaging is coming to a crossroad where it is no longer fiscally prudent to pack all desired functionality into a single die. While single-die packages will still be around, the high-end market is shifting towards multiple-die packages to reduce overall costs and improve functionality. This shif... » read more

Chiplet-Based Advanced Packaging Technology from 3D/TSV to FOWLP/FHE
By Technical Paper Link - 27 Aug, 2021 - Comments: 0

T. Fukushima, "Chiplet-Based Advanced Packaging Technology from 3D/TSV to FOWLP/FHE," 2021 Symposium on VLSI Circuits, 2021, pp. 1-2, doi: 10.23919/VLSICircuits52068.2021.9492335. Abstract: "More recently, "chiplets" are expected for further scaling the performance of LSI systems. However, system integration with the chiplets is not a new methodology. The basic concept dates back well over ... » read more

Advanced Packaging’s Next Wave
By Mark LaPedus - 20 May, 2021 - Comments: 0

Packaging houses are readying the next wave of advanced packages, enabling new system-level chip designs for a range of applications. These advanced packages involve a range of technologies, such as 2.5D/3D, chiplets, fan-out and system-in-package (SiP). Each of these, in turn, offers an array of options for assembling and integrating complex dies in an advanced package, providing chip custo... » read more
