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 4):
An n-type electrode comprising: the n-type ohmic electrode according to  claim 3  and\n a pad electrode at least provided on the n-type ohmic electrode, \n wherein the n-type electrode is sectioned into a contact region and a bonding region other than the contact region, \n part of the pad electrode in the contact region is provided on the n-type Al x Ga 1\u2212x N layer with the n-type ohmic electrode therebetween, and \n part of the pad electrode in the bonding region is provided on the n-type Al x Ga 1\u2212x N layer without the n-type ohmic electrode therebetween.
