Abstract (en)
[origin: WO9837586A1] A method for fabricating an electrical contact (12) on a surface (11) of a semiconductor comprising a group III element and nitrogen. The contact (12) is formed by depositing a metallic layer on the semiconductor surface and then annealing the layer at a tempeature greater than 400 DEG C for at least 4 hours. The method can be used to construct a Au/Ni contact on GaN semiconductor surface with substantially less resistivity than that obtained by conventional methods.
