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 2):
A processing apparatus for filling a germanium film in a recess on a substrate to be processed having an insulating film on which the recess is formed on its surface, comprising:\n a process vessel configured to accommodate the substrate; a gas supply part configured to supply a predetermined gas into the process vessel; an excitation mechanism configured to excite the predetermined gas; a heating mechanism configured to heat the interior of the process vessel; an exhaust mechanism configured to exhaust the interior of the process vessel so as to be in a depressurized state; and a control part configured to control the gas supply part, the excitation mechanism, the heating mechanism, and the exhaust mechanism, wherein the control part is configured to: control the interior of the process vessel to be in a predetermined depressurized state by the exhaust mechanism, and control the interior of the process vessel to have a predetermined temperature by the heating mechanism; forming a silicon film on a surface of the insulating film having the recess formed thereon; form a first germanium film on the silicon film so as to fill the recess by supplying a germanium raw material gas from the gas supply part into the process vessel; supply an etching gas containing an H 2  gas or an NH 3  gas from the gas supply part and excite the etching gas by the excitation mechanism; etch the first germanium film with the excited etching gas in the process vessel; and form a second germanium film on the first germanium film so as to fill the recess by supplying a germanium raw material gas from the gas supply part into the process vessel wherein, in the act of etching, the first germanium film is selectively etched with respect to the insulating film and the silicon film.
