Title: High withstand voltage semiconductor device
Inventor: INABA MASAMITSU
IPC: H01L29/732
Filed: 1993-10-28
Abstract: PURPOSE:To achieve a withstand voltage close to that at main junction by patterning the lead-out wiring traversing a channel stopper in stripe with a slit being made the vicinity of pn main junction and the channel stopper thereby preventing the withstand voltage from lowering due to the wiring formed on the channel stopper. CONSTITUTION:Upon application of reverse bias to a pn junction, a depletion layer 21 elongates toward a channel stopper 2 due to the field effect of a lead- out wiring 23 and a p-type inverted layer 20 elongates from a pn junction boundary 24 along the lead-out wiring. A slit is made from the vicinity of a fourth semiconductor region 4 to a second semiconductor region 2 thus patterning the lead-out wiring 23 in stripe. Since the lead-out wiring 23 is made thin, the p-type inverted layer 20 is restrained from reaching the channel stopper in the breadthwise direction by the depletion layer 21. This structure retards electrolytic concentration between the p-type inverted layer 20 and the channel stopper 2 thus providing a withstand voltage close to that of main junction.

Abstract: PURPOSE:To enable a detailed stress distribution to be obtained in the form of contour lines by providing an image pickup device for forming the photoelastic image of an object to be measured that is inserted in between a first polarizer and a quarter wavelength plate. CONSTITUTION:A parallel light beam reaches an image pickup device 7 via a first polarizer 4, a quarter wavelength plate 5 and a second polarizer 6.
