摘要: A method of manufacturing a semiconductor device includes the steps of (a) growing an InP layer (43A, 43B) on a surface (41) of starting growth, resulting in the InP layer (43A, 43B) having a convex structure, and (b) wet etching the InP layer (43A, 43B) by an etchant including hydrochloric acid and acetic acid, and thereby flattening a surface of the InP layer (43A, 43B).
