Abstract: PURPOSE:To fine an insulating region, and to form a transistor having low collector series resistance by using a trench isolation technique for the insulating region and diffusing an impurity by utilizing a trench at the time of the usage of the trench isolation technique. CONSTITUTION:Arsenic 4 is thermally diffused onto a P-type semiconductor substrate 1 to form a buried N<+> region 2, and an N-type epitaxial crystal layer 6 is grown on the region 2, and etched up to the buried N<+> region 2. Consequently, an insulating region is shaped through anisotropic dry etching, thus eliminating the need for heat treatment for a prolonged term, then fining the width of the insulating region. Phosphorus 10 is thermally diffused by utilizing the trenches. N<+> regions 11 shaped lower collector series resistance together with the previously formed buried N<+> region 2. The N<+> regions on the bottoms of the trench sections are etched through RIE, thin oxide films 12 are attached, and polysilicon 13 is grown to bury the trenches in the insulating regions 9. Boron 5 is diffused to shape a base region, and phosphorus is diffused to simultaneously form an emitter region and a collector region.

Inventor: MATSUOKA HIROKI
IPC: G01F1/68
Filed: 1984-09-03
Abstract: PURPOSE:To suppress a sacrifice of a response speed, to prevent an influence exerted on an engine, of a pulsation of air, and to prevent the hunting by constituting a titled device so that an output of a heat wire sensor is smoothed, only when a pulsation is generated in air in a suction path. CONSTITUTION:An air quantity in a suction path 7 pulsates in accordance with each process of suction, compression, explosion and exhaust in an engine body 8, when an opening of a throttle valve 3 exceeds a prescribed value and also it is within a prescribed range. A heat wire sensor 2 detects this air pulsation because its response speed is high. However, when the opening of the throttle valve 3 is smaller than the prescribed value, and its opening variation rate is outside the prescribed range, a pulsation of an output voltage V0 of the heat wire sensor 2 is a negligible degree. Therefore, a prescribed processing is executed by inputting an output of a throttle position sensor 18 to a controlling circuit 22, so that its output voltage is smoothed only in a state that the pulsation is such a large extent as cannot be disregarded.
