Abstract

PURPOSE: To obtain a Darlington transistor capable of accelerating the switching speed by forming a high impurity density region enclosing an emitter inserted between the base and the emitter of an initial stage transistor.
CONSTITUTION: An NPN transistor 1 having an N type region 12 as an emitter, P type regions 111, 112 as bases and an N type substrate 10 as a collector and an NPN transistor 2 having an N type region 14 as an emitter and the region 112 as a base are connected in a Darlington manner. Further, an NPN transistor 21 having an N type region 23 as an emitter, a P+ type region 22 and a P type region 115 as bases and the substrate 10 as a collector is formed, and the emitter 23 is connected to the base 111 of the transistor 1. Thus, the amplification factor of the transistor 21 becomes less than 1 due to the region 22, and high speed switching can be performed by rapidly releasing the stored charge of the base region from the emitter 23.
