Abstract

An atomic layer deposition (ALD) thin film deposition apparatus including a reactor in which a wafer is mounted and a thin film is deposited on the wafer, a first reaction gas supply portion for supplying a first reaction gas to the reactor, a second reaction gas supply portion for supplying a second reaction gas to the reactor, a first reaction gas supply line for connecting the first reaction gas supply portion to the reactor, a second reaction gas supply line for connecting the second reaction gas supply portion to the reactor, a first inert gas supply line for supplying an inert gas from an inert gas supply source to the first reaction gas supply line, a second inert gas supply line for supplying the inert gas from the inert gas supply source to the second reaction gas supply line, and an exhaust line for exhausting the gas from the reactor.
