Abstract
A device for carrying out a CVD process comprises a gas inlet element, which is arranged in a reactor housing and has a gas outlet plate, which faces a process chamber, comprises a porous material and has a multiplicity of gas outlet openings, which are fed with process gases from a gas distributing volume arranged in the gas inlet element. In order to improve production aspects of a gas inlet element, in particular for a CVD reactor with a large coating area, it is proposed that the porous material forms the core of the gas outlet plate, the surface segments of which that come into contact with the process gas are sealed.
