Abstract:
A method for reducing metal contamination performed after dry cleaning of a process chamber used for a film deposition process and before starting the film deposition process is provided. In the method, a temperature in the process chamber is changed from a first temperature during the dry cleaning to a film deposition temperature. Hydrogen and oxygen are activated in the vacuum chamber while supplying hydrogen and oxygen into the process chamber. An inside of the process chamber is coated by performing the film deposition process without a substrate in the process chamber after the step of activating hydrogen and oxygen.

Claim (Index 14):
A film deposition apparatus, comprising:\n a process chamber; a heater provided in the process chamber; a source gas supply part configured to supply a source gas into the process chamber; a hydrogen gas supply part configured to supply hydrogen gas into the process chamber; a oxygen gas supply part configured to supply oxygen gas into the process chamber and provided adjacent to the hydrogen gas supply part; and a controller configured to perform the following steps: activating hydrogen and oxygen in the vacuum chamber while changing a temperature in the process chamber from a first temperature during the dry cleaning to a predetermined temperature that is higher than a film deposition temperature by controlling the heater, the hydrogen supply part and the oxygen supply part; changing the temperature in the vacuum chamber from the predetermined temperature to the film deposition temperature by controlling the heater; and coating an inside of the process chamber by performing the film deposition process without a substrate in the process chamber after the step of changing the temperature in the vacuum chamber by controlling the source gas supply part and the oxygen gas supply part.
