Abstract: The method for doping a semiconductor includes the following steps in the following order: separation layer deposition step, in which a separation layer is deposited on the surface of a substrate, a mixture material source layer deposition step, in which a mixture material source layer including a mixture material is deposited on the separation layer, the mixture material of the mixture material source layer including a dopant substance, and annealing the substrate, the separation layer, and the mixture material source layer in an annealing step to arrange diffusion of dopant substance from the mixture material source layer to the substrate and to the separation layer.
