Patent number: 10181509Abstract: A high power vertical insulated-gate switch is described that includes an active region, containing a cell array, and a surrounding termination region. The termination region is for at least the purpose of controlling a breakdown voltage and does not contain any switching cells. Assuming the anode is the silicon substrate (p-type), it is desirable to have good hole injection efficiency from the substrate in the active region in the device's on-state. Therefore, the substrate should be highly doped (p++) in the active region. It is desirable to have poor hole injection efficiency in the termination region so that there is a minimum concentration of holes in the termination region when the switch is turned off. Various doping techniques are disclosed that cause the substrate to efficiency inject holes into the active region but inefficiently inject holes into the termination region during the on-state.Type: GrantFiled: August 4, 2016Date of Patent: January 15, 2019Assignee: PAKAL TECHNOLOGIES, LLCInventors: Richard A. Blanchard, Hidenori Akiyama, Vladimir Rodov, Woytek Tworzydlo
