The recent news about TSMC's packaging orders spilling over to companies like ASE and Powertech is a clear sign of a major bottleneck in the AI chip supply chain.
At the heart of this issue is the explosive demand for AI and high-performance computing (HPC). Even TSMC's CEO has stated it will be a "long time" before they can fully meet customer needs, with capacity expected to remain tight until around 2027. This official confirmation from the industry leader underscores a fundamental reality: demand is far outpacing current supply capabilities.
This leads to the first key link in the causal chain: TSMC's own capacity limits. While the company is making impressive progress, with its advanced 'CoWoS' packaging yield hitting over 98% and new factories being built, the truth is that they are still playing catch-up. The queue for their services remains long, making it inevitable that some orders must be sent elsewhere to meet deadlines.
So, the second link is the readiness of other players. This is where Outsourced Semiconductor Assembly and Test (OSAT) companies come in. Firms like ASE and Powertech have been preparing for this moment. For instance, ASE projects its advanced packaging revenue to exceed $3.5 billion by 2026 and is increasing its capital spending to meet this demand. They are not just passive recipients; they are actively investing to become the solution.
Finally, other market forces are reinforcing this trend. The rapid expansion of High Bandwidth Memory (HBM) production, essential for AI chips, also increases the need for advanced packaging. Additionally, U.S. export controls are concentrating the supply chain in compliant regions like Taiwan, further increasing the pressure on a few key players.
In short, the order spillover isn't an isolated event. It's the result of overwhelming demand, strategic investments by OSATs, and broader market dynamics. For now, the role of companies like ASE and Powertech is more critical than ever, directly influencing the pace and cost of the entire AI revolution.
