Thin-film deposition method
First Claim

1. 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.

Abstract
In a thin-film deposition method, a substrate is placed in a heat chamber having a pressure equal to or higher than an atmospheric pressure, and the substrate is heated in the heat chamber by supplying gas having a temperature higher than a room temperature by forced convection. The heated substrate is transferred from the heat chamber into a deposition chamber which is a vacuum chamber connected to the heat chamber directly or indirectly with a valve interposed therebetween. Then, a thin-film deposition is carried out on the substrate in the deposition chamber at a deposition temperature higher than the room temperature.
