Abstract: PURPOSE:To increase working speed by forming a semiconductor layer having a band gap larger than an emitter region or a collector region and an external base region between the emitter or collector region and the external base region. CONSTITUTION:An external base 56 and an emitter region 49 are shaped while the side faces of one sides thereof are faced oppositely, a Ga0.52In0.48P layer 50 having a band gap Eg larger than these regions 56 and 49 is formed between the external base region 56 and the emitter region 49 in the side faces of the regions 56 and 49, and buffer layer 42 composed of semi-insulating AlGaAs is shaped under the external base region 56 and a sub-emitter region 47. Since an intrinsic base region 59 and a collector region 58 in width W2 (<W3, W1) are formed so as to include the boundary of an intrinsic emitter region 48 and the external base region 56, the external base region 56 and the intrinsic base region 59 are brought into contact on one sides, and the width W2 of the intrinsic base region 59 is made smaller than that W3 of the external base region 56. Accordingly, base recombination currents, emitter resistance and emitter capacitance are reduced when the title bipolar transistor is manufactured in a collector-top type, and collector breakdown strength is increased and collector capacitance can be lowered when the bipolar transistor is produced in an emitter-top type.
