[News] Rumored AI Chip Demand Spurs Price Hikes at TSMC, UMC, ASE

TSMC’s CoWoS advanced packaging capacity shortage is causing limitations in NVIDIA’s AI chip output. Reports are emerging that NVIDIA is willing to pay a premium for alternative manufacturing capacity outside of TSMC, setting off a surge in massive overflow orders. UMC, the supplier of interposer materials for CoWoS, has reportedly raised prices for super hot runs and initiated plans to double its production capacity to meet client demand. ASE, an advanced packaging provider, is also seeing movement in its pricing.

In response to this, both UMC and ASE declined to comment on pricing and market rumors. In addressing the CoWoS advanced packaging capacity issue, NVIDIA previously confirmed during its financial report conference that it had certified other CoWoS packaging suppliers for capacity support and would collaborate with them to increase production, with industry speculation pointing towards ASE and other professional packaging factories.

TSMC’s CEO, C.C. Wei, openly stated that their advanced packaging capacity is at full utilization, and as the company actively expands its capacity, they will also outsource to professional packaging and testing factories.

It’s understood that the overflow effect from the inadequate CoWoS advanced packaging capacity at TSMC is gradually spreading. As the semiconductor industry as a whole adjusts its inventory, advanced packaging has become a market favorite.

Industry insiders point out that the interposer, acting as a communication medium within small chips, is a critical material in advanced packaging. With a broad uptick in demand for advanced packaging, the market for interposer materials is growing in parallel. Faced with high demand and limited supply, UMC has raised prices for super-hot-run interposer components.

UMC revealed that it has a comprehensive solution in the interposer field, including carriers, customed ASICs, and memory, with cooperation from multiple factories forming a substantial advantage. If other competitors are entering this space now, they might not have the quick responsiveness or abundant peripheral resources that UMC does.

UMC emphasized that compared to competitors, its competitive advantage in the interposer field lies in its open architecture. Currently, UMC’s interposer production primarily takes place in its Singapore plant, with a current capacity of about 3,000 units, with a target of doubling to six or seven thousand to meet customer demand.

Industry analysts attribute TSMC’s tight CoWoS advanced packaging capacity to a sudden surge in NVIDIA’s orders. TSMC’s CoWoS packaging had primarily catered to long-term partners, with production schedules already set, making it unable to provide NVIDIA with additional capacity. Moreover, even with tight capacity, TSMC won’t arbitrarily raise prices, as it would disrupt existing client production schedules. Therefore, NVIDIA’s move to secure additional capacity support through a premium likely involves temporary outsourced partners.
