The Future of Chip Manufacturing: TSMC’s CoWoS Capacity Expansion
In the fast-paced world of semiconductor technology, the Taiwan Semiconductor Manufacturing Company (TSMC) is making waves with its chip-on-wafer-on-substrate (CoWoS) packaging technology. A recent report from Taiwanese media suggests that TSMC is poised to double its CoWoS capacity by 2028, a move that could have significant implications for the industry. CoWoS is the go-to packaging solution for AI GPUs, with major players like NVIDIA relying on it for their cutting-edge products.
Intel’s Response: EMIB-T Technology
As the demand for CoWoS technology continues to surge, alternative solutions are emerging to address the supply shortage. One such technology is Intel’s EMIB-T, which offers a different approach to packaging compared to CoWoS. EMIB-T utilizes bridges within the organic substrate to connect components like logic and memory chips. In contrast, CoWoS employs an interposer with through silicon vias (TSVs) for enhanced communication between chips, resulting in higher bandwidth and lower latency.
TSMC’s Expansion Plans
According to a recent report from Taiwan, TSMC aims to ramp up its CoWoS capacity to 260,000 wafers per month by the end of 2028, doubling its current capacity. The expansion will focus on production facilities in Arizona and Taiwan, with Arizona capable of manufacturing the latest chip products. However, due to packaging constraints, these products need to be sent to Taiwan for packaging, as all of TSMC’s capacity is located in the island region.
On the other hand, analysts speculate that Intel’s EMIB-T capacity could reach between 15,000 and 20,000 wafers per month in 2027 and 40,000 to 45,000 wafers per month in 2028 when converted to the CoWoS equivalent.
Implications and Industry Response
The shortage in TSMC’s CoWoS capacity has created opportunities for other packaging companies like Amkor, UMC, and ASE to meet the rising demand. Each technology, whether CoWoS or EMIB-T, brings its unique strengths and applications, catering to different market needs and preferences.
