📊Executive Summary

The article discusses significant disruptions in the supply chain for BT substrate materials due to TSMC's increased demand for CoWoS chipmaking materials. Mitsubishi Gas Chemical (MGC), the largest supplier of BT substrate raw materials, has announced delays in shipments, which could lead to long-term shortages, particularly impacting NAND flash controller production. This situation is exacerbated by TSMC's expansion of CoWoS production capacity and the reliance on shared materials with BT substrates. As a result, companies like Phison, which supply NAND flash controllers, are likely to benefit from increased orders amidst these shortages, but pricing pressures are expected to rise as well....
