E08400 - SEMI E84 - Specification for Enhanced Carrier Handoff Parallel I/O Interface StdPbc-0816 SEMI MF1569-94 (Reapproved 1999) (firstDue to the migration to large wafer sizes, future semiconductor factories will use extensive automated material handling systems (AMHS) to transfer wafer carriers, including FOUPs and open cassettes, of increasing weight. The parallel input output (PI O) control signals between the production equipment and the AMHS must be better defined for more reliable and efficient carrier handoffs (load unload) at production equipment load ports. The purpose of
