<p>A thin film formation method to form an amorphous silicon film containing an impurity on a surface of an object to be processed in a process chamber that allows vacuum exhaust includes supplying a silane-based gas composed of silicon and hydrogen into the process chamber in a state that the silane-based gas is adsorbed onto the surface of the object without supplying an impurity-containing gas, supplying the impurity-containing gas into the process chamber to form the amorphous silicon film containing the impurity without supplying the silane-based gas, and performing the supplying of the silane-based gas and the supplying of the impurity-containing gas alternately and repeatedly such that the impurity reacts with the silane-based gas.</p> |
