Abstract
A treatment object containing any one of Cu/Ga, Cu/In and Cu—Ga/In is held in a heated state at a temperature Tfor a time Δtin such a state that a selenium source is introduced, thereby forming a selenide. Thereafter, a sulfur source is introduced to replace the atmosphere in the system with a sulfur atmosphere. In this state, the treatment object is held in a heated state at a temperature Tfor a time Δt. The temperature of the treatment object is then decreased to T, and, at that temperature, the treatment object is held in a heated state for a time Δt.
