ABSTRACT:
According to a semiconductor substrate treatment method, a surface or vicinity of a semiconductor substrate is deactivated by exposing the semiconductor substrate to a plasma atmosphere in which a gas containing at least hydrogen atoms is excited. A treatment is performed on the deactivated substrate surface. The treated substrate surface is activated by heating the semiconductor substrate.
