# TSMC — AI news & analysis

TSMC is the Taiwanese foundry that manufactures the advanced chips nearly every AI processor depends on.

- [GlobalFoundries to make US silicon interposers for TSMC's CoWoS](https://www.parallelquant.com/posts/globalfoundries-to-make-us-silicon-interposers-for-tsmc-s-cowos-8f18bf) (2026-10-08, Tom's Hardware): GlobalFoundries signed a five-year, $2 billion agreement to join TSMC's CoWoS advanced-packaging supply chain in the US. It will help produce interposers for AI and HPC accelerators without investing in leading-edge process nodes.
- [TSMC, Samsung, Intel back larger photomasks for next-gen lithography](https://www.parallelquant.com/posts/tsmc-samsung-intel-back-larger-photomasks-for-next-gen-lithography-a71f04) (2026-09-10, Tom's Hardware): TSMC, Samsung, and Intel are jointly supporting ASML's development of larger 6x12-inch photomasks for High-NA EUV lithography systems. The larger format would let chipmakers build big processors without stitching multiple exposures together, though the transition is expected to take years.
- [Arm unveils Neoverse CSS N4 chip platform with 128 cores per die](https://www.parallelquant.com/posts/arm-unveils-neoverse-css-n4-chip-platform-with-128-cores-per-die-cf7d13) (2026-09-08, Tom's Hardware): Arm introduced its next-generation Neoverse CSS N4 'Ranger' semi-custom platform, supporting up to 128 cores per die and 256MB of L3 cache on TSMC's N3P process. It's a significant increase over the previous Neoverse CSS N2 platform.
- [Intel passes 1 million wafers processed with High-NA EUV tools](https://www.parallelquant.com/posts/intel-passes-1-million-wafers-processed-with-high-na-euv-tools-d7626c) (2026-09-08, Tom's Hardware): Intel says it has processed more than one million wafers using High-NA EUV (extreme ultraviolet) lithography tools, surpassing the combined output of the rest of the semiconductor industry. The company is also developing larger 6x12 photomasks aimed at speeding production and lowering costs.
- [TSMC's fab equipment demand nearly doubles as AI drives expansion](https://www.parallelquant.com/posts/tsmc-s-fab-equipment-demand-nearly-doubles-as-ai-drives-expansion-8049fc) (2026-09-03, Tom's Hardware): TSMC's fab equipment requirements have nearly doubled over the past eight months as AI chip demand drives an unprecedented expansion in manufacturing capacity, pushing 2026 capital expenditure toward roughly $64 billion. That capex figure rose only about 15% year-over-year despite the surge in equipment needs, pointing to tool shortages across the supply chain.
- [LG enters chip packaging with new laser imaging machine](https://www.parallelquant.com/posts/lg-enters-chip-packaging-with-new-laser-imaging-machine-4b3b96) (2026-08-21, Tom's Hardware): LG has rolled out a laser direct imaging (LDI) lithography machine for chip packaging and high-density PCBs, a maskless process that trades some resolution for higher throughput. It arrives as TSMC's CoWoS advanced-packaging capacity, used to package AI accelerators like Nvidia's GPUs, remains constrained.
- [Taiwan to pay every resident $314 from AI server boom windfall](https://www.parallelquant.com/posts/taiwan-to-pay-every-resident-314-from-ai-server-boom-windfall-7d9fd8) (2026-08-19, Tom's Hardware): Taiwan will give roughly $314 in cash to every resident next year, funded by a $7.4 billion dividend in the 2027 central government budget. President Lai Ching-te tied the payout to the AI server boom, citing 11% GDP growth and a $903 billion export surge.
