CXMT Reportedly Struggles With HBM3E, Yields Are Only 25%
According to South Korean media, CXMT is struggling with HBM3E yields, with three out of four stacks defective. The company's front-end yields are around 30%, and back-end yields about 70%, resulting in 25% overall. CXMT uses only 3,000 TSVs per layer compared to competitors' 5,000-8,000. The low yields likely delay 12-Hi HBM production.
