Title: Semiconductor device
Inventor: MORI MUTSUHIRO
IPC: H01L29/739
Filed: 1989-09-20
Abstract: PURPOSE:To reduce a channel resistance and to realize a large electric current and a high breakdown strength by a method wherein a distance between insulated gates is made smaller than a width of the insulated gate. CONSTITUTION:In order to reduce a resistance (channel resistance) RP of an inversion layer in an IGBT or a power MOSFET of a mesh structure or a stripe structure, a depth of a rho layer 13 must be made shallow and, at the same time, its width, i.e., a circumferential length (channel width) of a gate 30, must be made wide. In the stripe structure by this invention, a distance LP between gates is made smaller than a width LG of the gate and the channel width can be made always large in various LG's. For example, in a semiconductor device whose breakdown strength is about 60 V, a depth of a rho layer 13 is 1 to 2mum and an LG is about 5mum. When an LP is set at 5mum or lower, a channel width of a stripe structure can be made wider than that in a mesh structure and a channel resistance RP can be made small. Consequently, a large electric current can be realized.
