At present, the latest IGBT7 maximum 65nm process, the current IGBT is basically more than 90nm process, the domestic Shanghai Microelectronics 90nm lithography machine can be done, there is no shipment is unclear, the current production line to see or imported, etching machine micro and North China Chuang can also be completed and can be shipped in bulk. Logically speaking, power semiconductors do not exist in the medium and long term.
