IPC: H01L29/08
Filed: 2000-01-21
Abstract: PROBLEM TO BE SOLVED: To make a high current to flow to a semiconductor device and to reduce the off-breakdown strength of the device. SOLUTION: P-type regions 5 are extendedly provided from a P-type base region 6 toward the direction of a P-type anode region 6, and an n-type region 4, which is used as one part of a drift region, is inserted between these regions 5. The region 4, which is held between the regions 5, of the drift region is formed so as to have a resistance lower than that of an n- region 3. In this way, the regions 5 are arranged on both sides of the drift region, whereby the drift region can be pinched off by depletion layers, which extend from the sides of the regions 5. Accordingly, an off-breakdown strength of a semiconductor device can be made high, and the region 4, held between the regions 5, is can be made low in resistance and a large current can be made to flow to the device.
