Recent developments suggest that TSMC’s CoWoS (Chip on Wafer on Substrate) and other sophisticated packaging solutions may face significant production slowdowns due to supply chain challenges stemming from Japan. A crucial supplier is reportedly scaling back the production of a fundamental component necessary for these advanced technologies.
Potential Production Disruptions for TSMC’s Advanced Packaging Solutions Amid Soaring Demand
The CoWoS technology developed by TSMC has played a pivotal role in the advancement of robust AI hardware, including NVIDIA’s accelerators. This packaging technique allows companies to enhance performance substantially by integrating multiple chiplets in a single unit. However, growing concerns have surfaced regarding a potential strain in the AI supply chain, prompting fears of a slowdown in advanced packaging production. Reports from Taiwan Economic Daily indicate that Asahi KASEI, a Japanese manufacturer of photosensitive polyimide (PSPI) crucial for advanced packaging, plans to reduce its supply to accommodate surging demand across the industry.
Asahi KASEI’s decision to prioritize PSPI supply for certain clients reflects the current struggle to meet overall demand. With the company being a critical player in the AI and semiconductor supply chains, a reduction in their output could result in significant delays for TSMC and its associated technologies, including CoWoS. Consequently, firms such as NVIDIA may be compelled to reassess pricing strategies or even experience further delays in their production timelines.
The pressing question now is whether TSMC will be adversely affected by this supply reduction. Asahi KASEI has established itself as one of TSMC’s most vital suppliers, and the two companies have significantly deepened their collaboration over the years. It is expected that Asahi will prioritize fulfilling orders from the Taiwanese giant, yet this supply cut is likely to ripple through the broader industry, affecting other advanced packaging providers such as ASE Technology, Samsung, and Intel. While these companies do not operate at the core of the mainstream supply chain, they too may face delays impacting a range of AI products.
In the past, NVIDIA’s CEO Jensen Huang has emphasized the absence of alternatives to TSMC’s CoWoS, underlining the company’s complete reliance on this Taiwan-based manufacturer. With the current surge in demand, it remains to be seen how TSMC will navigate these supply chain challenges and maintain production levels.
