450mm wafer transition needs collaboration and standards

摘要

As several leading chip makers assert a more specific time line for 450mm pilot line development, pre-compet-itive collaboration will continue to be the best path towards economic efficiency and industry rationality. While uncertainly about development funding remains, the supply chain is marshalling SEMI Standards task forces to advance agreements on the technical parameters for 450mm silicon wafers, physical interfaces, carriers, assembly and packaging. To date, SEMI has published six 450mm standards and 11 more are in the pipeline.
