Abstract:
There is provided an etching method which includes supplying an etching gas including an H 2  gas or an NH 3  gas to a target substrate having a germanium portion in an excited state; and etching the germanium portion.

Claim (Index 8):
An etching apparatus for etching a target substrate having germanium, comprising:\n a processing container configured to accommodate the target substrate; a gas supply part configured to supply a predetermined gas into the processing container; an excitation mechanism configured to excite the predetermined gas; a heating mechanism configured to heat an interior of the processing container: an exhaust mechanism configured to evacuate the interior of the processing container to bring the processing container into a depressurized state; and a controller configured to control the gas supply part, the excitation mechanism, the heating mechanism and the exhaust mechanism, wherein the controller is configured to: control the interior of the processing container to a predetermined depressurized state by the exhaust mechanism; control the interior of the processing container to a predetermined temperature by the heating mechanism; control the gas supply part to supply an etching gas containing an H 2  gas or an NH 3  gas; control the excitation mechanism to excite the etching gas; and etch the germanium of the target substrate inside the processing container using the etching gas in an excited state.
