Abstract:
A method for fabricating a light emitting semiconductor device, said method comprising:a step of forming a stacked structure by stacking a plurality of compound semiconductor layers containing at least an InxAlyGa1âˆ’xâˆ’yN (0&lE;x&lE;1, 0&lE;y&lE;1, x+y&lE;1) layer; a deposition step of depositing a first metal layer on at least a part of said InxAlyGa1âˆ’xâˆ’yN layer; an ion implantation step of injecting an impurity into said InxAlyGa1âˆ’xâˆ’yN layer via said first metal layer; and a heat treatment step of raising temperature to activate said impurity injected into said InxAlyGa1âˆ’xâˆ’yN layer to increase a surface carrier concentration in said InxAlyGa1âˆ’xâˆ’yN layer to decrease a contact resistance to said first metal layer.
