Abstract

PURPOSE:To reduce the time for heating substrates, by a method wherein a heating part has a space enclosed by a casing, and holes for connecting the space with the inside of a chamber, and gas is supplied to the space form the outside of the chamber. CONSTITUTION:Introduced gas 7 supplied to a gas pre-heating chamber 8 is heated by a heater 9, and introduced into the space 6B of a gas jetting type heater panel 6 through an introducing pipe 13. The introduced gas 7 is heated again by the radiation heat from a casing 6A of the panel 6, introduced into the inside of a vacuum chamber 1 through a lot of holes 6C, and comes into contact with both sides of substrates 3. As the result, both sides of each substrate 3 is heated by thermal conduction of the introduced gas 7 heated again, and heated also by the radiation heat of the casing 6A of the heater panel 6. Thereby the time for heating the substrates can be reduced.

[0003] Usually, the heating of the substrate 3 is performed in a state where the inside of the vacuum chamber 1 is depressurized to a film forming pressure or a state where the film forming pressure is lower than this. For example, the reduced pressure is 0.01 to several tens Pa. Both surfaces of the substrate 3 are heated by the radiant heat from the surface of the heater panel 4 and the heat conduction of the rare gas inside the vacuum chamber 1 to raise the temperature. For example, when a thin film transistor array large area glass substrate used for a liquid crystal display is used as the substrate 3, it takes several tens of minutes to raise the glass substrate to the temperature of the film forming process. During this tens of minutes, no film is formed on both surfaces of the substrate 3. Therefore, it has been desired to shorten the heating time of the substrate 3.

Conventionally, as a device for shortening the heating time of the substrate 3, a low pressure CVD apparatus disclosed in Japanese Patent Laid-Open No. 64-25423 is known. In this low pressure CVD apparatus, the inside of the vacuum chamber 1 was raised above the film forming pressure during the heating period of the substrate 3. Then, the substrate 3 is heated at a higher pressure than the film forming pressure. As a result, the substrate heating effect due to the heat conduction of the dilution gas inside the vacuum chamber 1 is enhanced, and the heating time of the substrate 3 is shortened.

However, in such a conventional low pressure CVD apparatus, the temperature of the introduced gas 7 is lower than the heating temperature of the substrate 3. That is, the temperature of the introduced gas 7 is room temperature until it is introduced into the vacuum chamber 1, and when it is introduced into the vacuum chamber 1, it is decompressed and further lowered. Therefore, the introduced gas 7 hinders the temperature rise of the substrate 3 during heating. Therefore, the shortening of the heating time of the substrate 3 was insufficient.
