3D Packaging
The reports about an insufficient supply of compute GPUs used for artificial intelligence (AI) and high-performance computing (HPC) servers became common in recent months as demand for GPUs to power generative AI applications exploded. TSMC admits that the biggest compute GPU supply bottleneck is its chip-on-wafer-on-substrate (CoWoS) packaging capacity, as it is used by virtually everyone in the AI and HPC business. The company is expanding CoWoS capacity but believes that its shortage will persist for 1.5 years. "It is not the shortage of AI chips," said Mark Liu, the chairman of TSMC, in a conversation with Nikkei. "It is the shortage of our CoWoS capacity. […] Currently, we cannot fulfill 100% of our customers' needs, but we try to support about 80%. We think...
