Process gas discharged from a bypass pipe to a gas exhaust system can be prevented from diffusing back to the inside of a process chamber without having to install a dedicated vacuum pump at the downstream side of the bypass pipe. The substrate processing apparatus includes a process chamber accommodating a substrate, a gas supply system supplying process gas from a process gas source to the process chamber for processing the substrate, a gas exhaust system configured to exhaust the process chamber, two or more vacuum pumps installed in series at the gas exhaust system, and a bypass pipe connected between the gas supply system and the gas exhaust system. The most upstream one of the vacuum pumps is a mechanical booster pump, and the bypass pipe is connected between the mechanical booster pump and the rest vacuum pumps located at a downstream side of the mechanical booster pump.

Disclosed herein are a method of depositing a thin film and a method of manufacturing a semiconductor using the same, having high selectivity by increasing etching resistance while an extinction coefficient associated with anti-reflectivity is maintained low. The method of depositing a thin film according to the invention includes (a) depositing an carbon anti-reflective film on the bottom film of a substrate; and (b) adding a compound containing nitrogen (N), fluorine (F) or silicon (Si) to the surface or the inner portion of the carbon anti-reflective film, to deposit a thin film of a-C:N, a-C:F or a-C:Si, having high selectivity, to a thickness from 1 to 100 nm using an atomic layer deposition process. Therefore, an ultrathin film having etching resistance is formed on or in the carbon anti-reflective film and the density and compressive stress of the carbon anti-reflective film are increased, thus increasing etching selectivity.
