摘要:
The invention relates to a method for depositing thick III-V semiconductor layers on a non-III-V substrate, particularly a silicon substrate, by introducing gaseous starting materials into the process chamber of a reactor. The aim of the invention is to carry out the crystalline deposition of thick III-V semiconductor layers on a silicon substrate without the occurrence of unfavorable lattice distortions. To this end, the invention provides that a thin intermediate layer is deposited at a reduced growth temperature between two III-V layers.
