IPC: H01L29/74
Filed: 1978-02-08
Abstract: PURPOSE:To enable the pinch-off for the main current path with small amount of the gate voltage and thus to increase the voltage blocking gain by forming the base region with the thin 1st part including the gate region and the 2nd part which is adjacent to the anode region and features a lower relative resistance than the 1st part. CONSTITUTION:N-type layer 21 is formed through diffusion on the back of N<->-type Si substrate 100, and stripe-type P-type region 61 is formed through diffusion and selectively on the surface each. Then N-type layer 23 is epitaxial-grown on the entire surface including layer 21 and region 61, with shallow P<+>-type region 601 formed through diffusion at the position to oppose to region 61. After this, N<+>- type layer 101 is formed through diffusion within layer 21 on the back with the heat treatment applied to the whole part to make region 601 and layer 101 extend up to inside substrate 100. Thus, region 601 is connected up to nearly the center of region 61, and gate region 6 is formed with region 601 and 61. At the same time, layer 101 is increased up to the prescribed depth to be turned to anode layer 1, and then N<+>-type cathode region 3 is formed through diffusion along the gate region.

Abstract: PROBLEM TO BE SOLVED: To reduce higher harmonic components generated in a power system by a PWM converter through the means of a PWM converter for reducing higher harmonic, without using a current detector or a filter and thereby reduce the cost. SOLUTION: PWM converters 4a, 4b execute a PWM control through control circuits 11a, 11b with a fundamental wave of an AC voltage, which should be generated at the input side of the converters as a modulated wave and then perform a PWM operation based on gate signal obtained.
