TSMC Preps 6x Reticle Size Super Carrier Interposer for Extreme SiP Processors

As part of their efforts to push the boundaries on the largest manufacturable chip sizes, Taiwan Semiconductor Manufacturing Co. is working on its new Chip-On-Wafer-On-Substrate-L (CoWoS-L) packaging technology that will allow it to build larger Super Carrier interposers. Aimed at the 2025 time span, the next generation of TSMC's CoWoS technology will allow for interposers reaching up to six times TSMC's maximum reticle size, up from 3.3x for their current interposers. Such formidable system-in-packages (SiP) are intended for use by performance-hungry data center and HPC chips, a niche market that has proven willing to pay significant premiums to be able to place multiple high performance chiplets on a single package.

"We are currently developing a 6x reticle size CoWoS-L technology with Super Carrier interposer technology," said said Yujun Li, TSMC's director of business development who is in charge of the foundry's High Performance Computing Business ...
