Title: High withstand voltage semiconductor device
Inventor: OBA MASATAKA
IPC: H01L29/74
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce voids in a resin due to the foaming from an air gap caused by the deformation of a packing which is brought about with thermal distortion or the like by providing one or more grooves in the outer circumferential part of a cylindrical packing in an annular insulating body in which an insulating resin is injected into an air gap formed of a disk-like semiconductor base body and a jig. SOLUTION: The structure of a device is devised. The means comprises the step of forming a disk-like semiconductor base body (a silicon substrate) 11 having one or more pn junctions and a cylindrical packing 14 molded out of an insulating material and having a larger inner diameter than the external form of the silicon substrate 11. An insulating resin of flowability is filled in an air gap 16 formed of jigs 12, 13 including both outside and inside surfaces of the outer circumferential end part of the silicon substrate 11 and solidified to form an annular insulating body. In the annular insulating body, one or are ring-like grooves 111 are provided in the outer circumferential part of the annular packing 14. Therefore, since undesirable deformation of the packing can be prevented, a dead space does not exist, so that the generation of voids may be prevented.
