Summary:PROBLEM TO BE SOLVED: To reduce contact resistance of an electrode in a semiconductor electronic device wherein a contact layer of the electrode is not formed by selective growth. SOLUTION: In the semiconductor electronic device including at least a nitride chemical compound semiconductor layer and an electrode in an area including a part of at least a surface of the nitride semiconductor layer, an impurity is added and band gap energy is smaller than that of the nitride semiconductor layer other than the area, and the electrode is configured in contact with the area. Furthermore, the nitride chemical compound semiconductor layer contains AlxGa1-xN (0≤x<1), and the impurity contains at least one of In, As, P, Sb. COPYRIGHT: (C)2005,JPO&NCIPI
