Title: High withstand voltage semiconductor device
Inventor: MIURA SHOJI
IPC: H01L29/732
Filed: 1992-12-25
Abstract: PURPOSE:To provide a high withstand voltage semiconductor device in which withstand voltage is enhanced while realizing high integration. CONSTITUTION:PN junction between an embedded collector region 3 and a collector withstand voltage region 4 is reversely biased and the depletion layer thereof reaches a side isolation insulator region 9 for dielectrically isolating the side face of the semiconductor withstand voltage region 4. A polysilicon region 8 contiguous to the collector withstand voltage region 4 while sandwiching the side face isolation insulator region 9 has a potential closer to that of a base region 5 than that of the embedded collector region 3. Consequently, the depletion layer in the collector withstand voltage region 4 between the side face of the base region 5 and the side face isolation insulator region 9 is affected by the low potential from both sides of the base region 5 and the polysilicon region 8 and concentration of electric field is relaxed in the vicinity of the corner part between the side face and the bottom face in the base region 5. Consequently, avalanche breakdown is suppressed at that part resulting in the enhancement of withstand voltage.
