Patent JP-H06204481-A (JP)
Title: Insulated-gate semiconductor device and manufacture thereof
Inventor: TAKAHASHI HIDEKI
IPC: H01L21/331
Filed: 1993-09-21
Abstract: PURPOSE:To obtain an insulated-gate type semiconductor device having a reduced on resistance and yet improved resistance to breakage by providing a fifth semiconductor region having an higher concentration of impurity of a second conductivity type than a second semiconductor region does. CONSTITUTION:A buffer layer 21 having a relatively low n-type impurity concentration and high concentration n-type semiconductor regions 22, are placed in parallel between an n-type semiconductor layer 3 and a p-type semiconductor layer 1. In hole movement from the p-type semiconductor layer 1 to the n-type semiconductor layer 3 at a low collector current Ic, holes move selectively avoiding the high concentration semiconductor regions 22. At a high collector current Ic, the path which the collector current Ic takes is limited to areas where there is no high concentration n-type semiconductor regions, and that dominantly has effect to limit the collector current Ic. Therefore, the on resistance of the device is lower than in cases where the fifth semiconductor layer were not provided. At a high current this suppresses the current and improves the breaking strength of the device.
