Title: Semiconductor device
Inventor: OHATA TOSHIBUMI
IPC: H01L21/331
Filed: 1993-05-18
Abstract: PURPOSE:To enhance the high resistance of termination structure by forming deeply a low concentration p layer in such a fashion that it may cover the corners of a main coupling p layer and specifying the distance between the tip of the main coupling layer in the surface transverse direction and the tip of an electrode from the main coupling layer. CONSTITUTION:An insulation film 3, an n buried layer and an n type board 1 are installed to a support board 4, thereby forming a main coupling p layer 6 and a low concentration p layer 7 for field relaxation in the horizontal direction and installing an electrode 5 to the main coupling p layer 6 by way of a part of an insulation layer 9 where the low concentration p layer 7 is formed deeply in such a fashion that it may cover the corners of the main coupling p layer 6. The distance LFP between the tip of the main coupling p layer 6 in the surface horizontal direction and the end of the low concentration P layer is arranged to not be identical to the distance LP between the tip of the main coupling p layer 6 and the end of the low concentration P layer. This construction makes it possible to reduce an increase in a device area to be occupied for the termination and create termination structure suitable to enhanced higher resistance.
