Semiconductor International ; The move to larger wafer sizes is, to some, inevitable. Going back to 1975, the industry moved fairly rapidly from 100 mm to 125 and 150 mm, with each transition taking about three years. The move from 150 to 200 mm took a little longer--five years--and the move to 300 mm took eight years. Today,
