Inotera Memories, which is currently migrating from its own DDR2 processes to Micron Technologies stack DDR3 processes at the 50nm node has placed a multiple systems order with Hitachi Kokusai Electronics, worth approximately US$21.9 million. Hitachi Kokusai is a long-standing supplier of vertical furnaces to Inotera’s 300mm DRAM fabs.
Inotera has previously used several vertical furnace suppliers rather than being dependent on a single supplier. Inotera recently placed an order with TEL, which has previously been a supplier of diffusion furnaces to the Taiwan-based DRAM producer.
