Abstract
A fabrication method of fabricating a structure capable of being used for generation or detection of electromagnetic radiation includes a forming step of forming a layer containing a compound semiconductor on a substrate at a substrate temperature below about 300° C., a first heating step of heating the substrate with the layer in an ambience containing arsenic, and a second heating step of heating the substrate with the layer at the substrate temperature above about 600° C. in a gas ambience incapable of chemically reacting on the compound semiconductor. Structures of the present invention capable of being used for generation or detection of electromagnetic radiation can be fabricated using the fabrication method by appropriately regulating the substrate temperature, the heating time, the gas ambience and the like in the second heating step.
