China's fast-rising AI models are running into a compute supply bottleneck as demand for advanced packaging substrates surges, with ByteDance reportedly preparing to spend CNY100 billion (US$14.9 billion) a year on large-scale chip substrate purchases by 2030. Supply chain sources say the scramble for packaging substrate capacity is intensifying across Huawei HiSilicon, Hygon Information Technology, ByteDance, and major outsourced semiconductor assembly and test (OSAT) players, even as the industry races to expand output.
DeepSeek CEO Liang Wenfeng said during a call with investors that he aims to rely on Huawei chips to train the startup's models in the future, and that a batch of training chips from Huawei are set to begin arriving at his company as early as the fourth quarter of 2026.
The labor dispute at Micron Taiwan continues to escalate after Micron and the Taiwan Taoyuan Union failed to reach agreement at a second mediation meeting on September 21, 2026. The union said the company has not presented a concrete profit-sharing plan and announced it will launch a strike vote under the Act for Settlement of Labor-Management Disputes, while Micron said it will keep talking and coordinating but must still go through board procedures.
Samsung Electronics is considering expanding its 4nm foundry capacity as rising HBM4 base-die demand pushes existing capacity to full utilization, South Korea's Money Today reported on September 21. The company is also reviewing whether to build a new 2nm production line for base dies in future HBM5 products.
Rising demand for advanced packaging tied to AI and high-performance computing (HPC) is driving development at Baipu Industrial Park in Kaohsiung, where construction has formally begun on what is billed as Taiwan's first advanced packaging supply-chain cluster. Led by TSMC, the park's first phase has already been fully allocated, and a groundbreaking ceremony on September 21 drew more than 20 semiconductor companies, including TSMC, Foxconn, and ASE.
China's silicon carbide (SiC) end-market demand is expanding rapidly, driven by high-voltage charging infrastructure and AI servers. The surge in orders has tightened SiC wafer capacity in China, and some offshore companies seeking foundry partners there have reportedly been turned away, pushing spillover business toward Taiwan, where Episil, HYS, and Diodes are among the names cited as potential beneficiaries.
MediaTek has introduced a new chip aimed at premium, ultra-portable Googlebook devices, underscoring how next-generation AI, battery life, and wireless performance could shape consumer computing worldwide. The Dimensity CX C10 Max is built for thinner systems, faster multitasking, and privacy-focused Gemini features in markets beyond Asia.
Advanced packaging remains one of the semiconductor industry's hottest technology areas in 2026. In Taiwan, terms such as co-packaged optics (CPO), chiplets, and glass substrates are increasingly common as packaging moves deeper into system-level design.
