A method for treating a substrate and a substrate

摘要

A method for treating a compound semiconductor substrate, in which method in vacuum conditions a surface of an In-containing lll-As, lll-Sb or lll-P substrate is cleaned from amorphous native oxides and after that the cleaned substrate is heated to a temperature of about 250-550 °C and oxidized by introducing oxygen gas onto the surface of the substrate. The invention relates also to a compound semiconductor substrate, and the use of the substrate in a structure of a transistor such as MOSFET.
