Patent ID: 6933009

Claim:
A thin-film deposition method, comprising: placing a substrate in a heat chamber having a pressure equal to or higher than an atmospheric pressure; heating the substrate at least to a deposition temperature in the heat chamber by supplying gas having a temperature higher than a room temperature by forced convection; transferring the heated substrate from the heat chamber into a load-lock chamber which is a vacuum chamber connected to the heat chamber directly or indirectly with a first valve interposed therebetween, in which a temperature-decrease prevention mechanism controls a temperature of the substrate to be equal to or higher than the deposition temperature; transferring the heated substrate from the load-lock chamber into a deposition chamber which is a vacuum chamber connected to the load-lock chamber directly or indirectly with a second valve interposed therebetween, and carrying out a thin-film deposition on the substrate in the deposition chamber at the deposition temperature higher than the room temperature.
