Abstract:
A method of heat-treating a nitride compound semiconductor layer, comprising heat-treating a nitride compound semiconductor layer doped with a p-type impurity in a state where the heating time period t (unit: minute) and the heating temperature T (unit: K) satisfy conditions of t &lE;100 and the following equation (1),T&gE;&agr;/[ln [{square root over (t)})+ln(D0)âˆ’ln (C)]â€ƒâ€ƒ(1) wherein &agr;is a coefficient that is 1.04Ã—10 4, ln (D0)is a coefficient that is 53and C is a carrier concentration (unit: cmâˆ’3) of the nitride compound semiconductor layer after the heat treatment thereof, in which the heating temperature T (K) is brought into a state where the condition of 473(K)&lE;T <673(K) is satisfied.
