Abstract

PURPOSE: To produce a semiconductor having high reliability with forming a protection layer in where, when a drain is set on the semiconductor base to separate the semiconductor element, special step is made on the drain and the whole drain is completely covered with a filler.
CONSTITUTION: An n-type region 2 is formed on the p-type semiconductor base 1 with a method, and the pn junction 3 is formed between collector bases. Further, plural semiconductor elements are formed by forming the emitter region with diffusion of p-type impurity in the region 2. The drain 4 having a stair part 5 is made on the pn junction 3. The stair 5 should be shallower than the pn junction 3 and the surface of inside wall also should be rough. The drain 4 is completely covered with filler 7 made of metal oxides etc. and it is allowed to spread the filler 7 from the stair part 5 over the insulation fiom 6. The stable and completed protection layer 7a is formed with heat treatment and also separates between the semiconductor elements.
