摘要:
In a semiconductor device comprising at least one bipolar transistor (45) and a VIP isolating layer (43) which are formed in both an epitaxial layer (33) and a semiconductor substrate (31), an impurity-introduced region (37) having the same conductivity type as that of the semiconductor substrate (31) is formed so asto surround the V-groove (36). A buried layer (32) of the bipolartransistor comes into contact with the VIP isolating layer (39,40) to divide the impurity-intorduced region into two parts, one of which is combined with a base region (37) and the other one of which serves as a channel stopper (38).
