Compound semiconductor surface stabilizing method, semiconductor laser device fabricating method using the stabilizing method, and semiconductor device

摘要

In a compound semiconductor surface stabilizing method, a compound semiconductor is immersed in a solution containing sulfur ions, and then, the compound semiconductor is immersed in a solution containing cations, which react with sulfur to form a sulfide. These immersing steps form a sulfur layer and a sulfide layer in this order on a surface of the compound semiconductor.
