TSMC expands not only CoWoS-S but the emerging CoWoS-L capacity.

August 04, 2023

Key Takeaways:

Longtan plant (AP3) is facing production constraints, leading to a shift in production expansion efforts to the Zhunan plant (AP6).
In addition to CoWoS-S expansion, CoWoS-L expansion is underway at Zhunan plant (AP6B) for 2H24 production.
CoWoS-L offers area scalability with RDL and silicon embedded interconnects for packaging exceeding 3~3.5x reticle size, becoming TSMC’s primary 2.5D packaging after Y2025.
