Abstract:
A method of filling a germanium film in a recess on a substrate to be processed having an insulating film on which the recess is formed on a surface of the substrate, includes forming a first germanium film so as to fill the recess by supplying a germanium raw material gas to the substrate, etching the first germanium film with an etching gas containing an excited H 2  gas or NH 3  gas, and forming a second germanium film on the first germanium film so as to fill the recess by supplying a germanium raw material gas.

Claim (Index 1):
A method of filling a germanium film in a recess on a substrate to be processed having an insulating film on which the recess is formed on a surface of the substrate, comprising:\n forming a silicon film on a surface of the insulating film having the recess formed thereon; forming a first germanium film on the silicon film so as to fill the recess by supplying a germanium raw material gas to the substrate; etching the first germanium film with an etching gas containing an excited H 2  gas or NH 3  gas; and forming a second germanium film on the first germanium film so as to fill the recess by supplying a germanium raw material gas wherein, in the act of etching, the first germanium film is selectively etched with respect to the insulating film and the silicon film.
