Abstract:
Provided is a method of producing an n-type ohmic electrode that can form a good ohmic contact with an n-type Al x Ga 1−x N (0.5≤x≤1) layer. The method of producing an n-type ohmic electrode includes: a first step of forming a first layer  11  made of one of Ti and Hf on a surface of a layer  30 ; a second step of forming a second layer  12  made of Sn on the surface of the first layer  11 ; a third step of forming a third layer  13  made of one of V and Mo on the surface of the second layer  12 ; a fourth step of forming a fourth layer  14  made of Al on the surface of the third layer  13 ; and a fifth step of performing heat treatment on the first layer  11 , the second layer  12 , the third layer  13 , and the fourth layer  14.

Claim (Index 1):
A method of producing an n-type ohmic electrode, comprising:\n a first step of a first metal layer made of one of Ti and Hf on a surface of an n-type Al x Ga 1\u2212x N layer, where x satisfies 0.5\u2264x\u22641; a second step of forming a second metal layer made of Sn on a surface of the first metal layer; a third step of forming a third metal layer made of one of V and Mo on a surface of the second metal layer; a fourth step of forming a fourth metal layer made of Al on a surface of the third metal layer; and a fifth step of performing heat treatment on the first metal layer, the second metal layer, the third metal layer, and the fourth metal layer.
