Abstract: PURPOSE:To reduce base series resistance and the thickness of a base layer, and to improve characteristics such as cut-off frequency by atomic plane-doping an impurity to the base layer and bringing the activation temperature of an impurity ion-implanted to a base contact region to the growth temperature or less of the base layer.

That is, the epitaxial growth temperature (a substrate temperature) of a semiconductor layer to which atomic plane doping is conducted is set generally at a value close to a temperature, which does not exceed a temperature at an upper limit where a doping impurity is not thermally diffused. When the implanted impurity is activated after the setting of the epitaxial growth temperature is activated, the heat treatment temperature of the impurity is brought to a temperature close to a value, which does not exceed the growth temperature of the semiconductor layer, thus activating the impurity without disturbing the state of atomic plane doping.
