摘要:
A process of manufacturing a semiconductor device includes the steps of forming a stacked structure of a first III-V compound semiconductor layer containing In and having a composition different from InP and a second III-V compound semiconductor layer containing In. The second III-V compound semiconductor layer is formed over the first III-V compound semiconductor layer and growing an InP layer at regions adjacent the stacked structure to form a stepped structure of InP. The process further includes the step of wet-etching the stepped structure and the second III-V compound semiconductor layer using an etchant containing hydrochloric acid and acetic acid to remove at least the second III-V compound semiconductor layer.
摘要:
An n type InP buried layer 22 with Se or S added in an above 5null1018 cmnull3 concentration is formed on an active layer mesa stripe 18 having a surface with an SiO2 film 16 formed on at a peripheral part of the mesa stripe 18 other than the surface with the SiO2 film 16 formed on. Accordingly, the buried layer can be grown without the over growth.

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