Abstract

PURPOSE:To eliminate formation of a barrier against both of majority and minority carriers in a semiconductor device by ohmically attaching a metallic electrode through a semiconductor layer with the same and reverse conducting type electrodes of high impurity density to a semiconductor layer. CONSTITUTION:A metallic electrode 3 is ohmically attached through a semiconductor layer 5 with electrode to a semiconductor layer 1. In this case, the layer 5 has the same conducting type as the layer 1 and consists of a layer 6 having higher impurity density than the layer 1, and a layer 7 having reverse conducting type to the layer 1 and higher impurity density than the layer 1. In this manner, even if there is a potential barrier to the minority carrier between the layers 1 and 6, there exists substantially no barrier against the majority carrier. Even if there exists reverse conducting type potential barrier against the majority carrier between the layers 1 and 7, the minority carrier is absorbed to the layer 7, and there is no barrier thereto. Therefore, there is formed no barrier against both the majority and the minority carriers.
