Unified tool communication specification for 300 mm automated fab

In 300 mm diameter wafer fabrication line, concrete infrastructure that enables high degree of line operation is essential to minimize the cost and the risk of new 300 mm fab infrastructure and integration. Equipment online communication is an essential technology as fab infrastructure. Based on CIM-GJG and SEMI standards, Selete (Semiconductor Leading Edge Technologies, Inc.) has been developed unified process tool communication specification and its test specification at implementation level. These specifications will be used as base specifications among device makers and give directions of design and implementation at equipment suppliers.
