                    1. Introduction: From Wafer Diameter to Industrial Capability In semiconductor technology, wafer diameter has historically served as a reliable indicator of manufacturing maturity. Each major transition in wafer size\u2014from 150 mm to 200 mm, and later to 300 mm\u2014has marked a shift from laboratory-scale innovation to industrial-scale production.
