Title: Semiconductor device
Inventor: IIJIMA TETSUO
IPC: H01L29/78
Filed: 1991-05-24
Abstract: PURPOSE:To enable a vertical power MOSFET to be enhanced in switching speed and breakdown strength. CONSTITUTION:A vertical power MOSFET is provided with many P-type MOS wells 3 which form MOSFETs and are provided on the primary face of a chip 35 and a peripheral well 4 provided around the MOSFETs. The peripheral well 4 is set lower than the MOS well 3 in concentration. Therefore, when a forward current flows through a built-in diode 12, carriers injected into a semiconductor substrate 1 from the peripheral well 4 are lessened in amount, so that the built-in diode 12 is shortened in inverse recovery time. As the stored carrier is small in amount, a semiconductor of this design can be enhanced in breakdown strength.
