Abstract
PURPOSE: To reduce the bare spreading resistance and to improve the high-frequency characteristic by forming, in the surface part of collector adhesion and emitter adhesion part, high density impurities diffusion area of conductive shape same as a base layer at a small depth.
CONSTITUTION: A N- shape layer 2 in a P shape base plate 1, a P shape collector layer 3, a P shape emitter layer 4, a N+ shape base contact area 5, an embedded N+ shape layer 6 and a separating layer 7 are formed. A N+ shape diffusion layer 8 diffused in high density and shallowly the impurities of the conductive shape same as the N+ shape layer 2, is in contact with the N+ shape base contact area 5 and it is formed projecting up to the upper part of the collector layer 3 and the emitter layer 4. That is to say, a resistance r5 of this N+ shape diffusion layer 8 is considered to be connected in parallel to the resistance in series connection of r1, r2, r3 and r4. Thus, base spreading resistance can be reduced.
