A charged particle beam apparatus is provided that enables faster semiconductor film deposition than the conventional deposition that uses silicon hydrides and halides as source gases. The charged particle beam apparatus includes a charged particle source 1, a condenser lens electrode 2, a blanking electrode 3, a scanning electrode 4, a sample stage 10 on which a sample 9 is mounted, a secondary charged particle detector 8 that detects a secondary charged particle 7 generated from the sample 9 in response to the charged particle beam irradiation, a reservoir 14 that accommodates cyclopentasilane as a source gas, and a gas gun 11 that supplies the source gas to the sample 9.
