Chinese storage makers are moving up the value chain from chip packaging into wafer-level operations. Shanghai-listed Biwin Storage Technology will invest 4.5 billion yuan (US$672 million) in phase three of its advanced packaging and testing project in Dongguan, exceeding the 3.09 billion yuan of the first two phases combined.

The project is still in customer sampling, process verification and small-batch production with no mass-production revenue yet. Biwin expects monthly capacity to more than triple to 10,000 wafers by end-2027, adding to its traditional memory and SiP packaging base in Huizhou.
