First Claim
Patent Images
1. A substrate processing apparatus comprising:
- a reaction chamber;
a substrate holder constructed and arranged to hold at least one substrate in said reaction chamber; and
,a gas injector system constructed and arranged to provide a process gas to the interior of the reaction chamber and provided with a gas control system constructed and arranged to control the process gas flow from a source pipe;
wherein the gas injector system comprises a first and second injector for the same process gas and the gas control system is constructed, arranged, and/or programmed to provide the flow of the process gas from the source pipe to one of the first and second injectors while restricting a flow of the same process gas to another of the first and second injectors.

Abstract
A substrate processing apparatus with a reaction chamber and a substrate holder constructed and arranged to hold at least one substrate in said reaction chamber is provided. A first and second gas injector provides a process gas to the interior of the reaction chamber from a source pipe. A gas control system provides a flow of process gas from the source pipe to the first injector while restricting a flow of the same process gas from the source pipe to the second injector.
