Filed: 1987-04-28
Abstract: PURPOSE:To contribute to the enhancement of circuit integration by a method wherein a thick insulating film is formed on the bottom of an isolating trench and a thin insulating film is formed on the trench side walls. CONSTITUTION:A semiconductor substrate 1 is provided with a trench 3 covered by a thick insulating film 5. A resist 6 is applied to the semiconductor substrate 1, filling up the trench 3. A directional energy beam such as a soft X-ray beam R is projected into the trench, from a direction a prescribed angle inclined from the normal line of the semiconductor substrate 1. A portion of the resist 6 positioned on the bottom of the trench 3 remains not exposed to the beam R with the sidewalls serving as shades. The resist 6 is retained therefore only on the bottom of the trench 3 after development. The resist 6 serves as a mask in a selective etching process wherein the thick insulating film 5 is removed from the side walls of the trench 3. But the film 5 is retained on the bottom. A thin insulating film 8 is formed on the thus-exposed side walls of the trench 3. In this way, the bottom of the trench 3 is covered by a thick insulating film 50 while the side walls thereof are covered by a thin insulating film 8. This design contributes to the enhancement of circuit integration.

Filed: 1983-06-13
Abstract: PURPOSE:To generate an exponential function through extremely simple constitution by feeding the output of a variation rate limiter back to the variation rate setting part of the variation rate limiter. CONSTITUTION:The variation rate limiter 30 limits the variation rate of an input signal E1, and a feedback circuit 40 feeds the output E0 of the variation rate limiter 30 back to its variation rate setting part. When the output E0 is small, its variation rate set value is also small, so the output variation rate is small; when the output E0 is large, the variation rate set value is large and the variation rate of the output is large.
