Title: Semiconductor device
Inventor: TAKAHASHI KAZUHISA
IPC: H01L21/331
Filed: 1979-06-01
Abstract: PURPOSE:To obtain a high voltage resistance device by the method wherein a PN-junction to which a reverse bias is to be applied is formed along the inner wall of a depression formed on a semiconductor substrate, and the breakdown voltage in the surrounding part is raised. CONSTITUTION:After a depression is formed on N<+>-type InP substrate 21 by mesa- etching, P-type InGaAsP active layer 22 and P<+>-type InP layer 23 are epitaxially formed. Then, the edge part of the bottom of the depression is made thick. Next, by lapping the upper surface, the exposed part of the PN-junction is covered with SiO2 film 25. By this structure, a depletion layer expands inwardly in the vertical direction on the inner wall of the depression at the time when a reverse bias is applied. In the edge part of the bottom, it expands wider than in the center part. Consequently, the breakdown voltate becomes higher in the edge part of the bottom, so that it is possible to obtain a device of high voltage resistance easily.
