TSMC today announced it has collaborated with Broadcom on enhancing the Chip-on-Wafer-on-Substrate (CoWoS ) platform to support the industry's first and largest 2X reticle size interposer. With an area of approximately 1,700mm2, this next generation CoWoS interposer technology significantly boosts computing power for advanced HPC systems by supporting more SoCs as well as being ready to support TSMC's next-generation five-nanometer (N5) process technology.

This new generation CoWoS technology can accommodate multiple logic system-on-chip (SoC) dies, and up to 6 cubes of high-bandwidth memory (HBM), offering as much as 96 GB of memory. It also provides bandwidth of up to 2.7 terabytes per second, 2.7 times faster than TSMC's previously offered CoWoS solution in 2016. With higher memory capacity and bandwidth, this CoWoS solution is well-suited for memory-intensive workloads such as deep learning, as well as workloads for 5G networking, power-efficient datacenters, and more. In addition to offering additional area to increase compute, I/O, and HBM integration, this enhanced CoWoS technology provides greater design flexibility and yield for complex ASIC designs in advanced process nodes.
