CVD REACTOR AND METHOD FOR CONTROLLING THE SURFACE TEMPERATURE OF THE SUBSTRATES
In a CVD reactor and a method for the open-loop/closed-loop control of the surface temperature of substrates arranged therein, the substrates lie on substrate-retaining elements, which are each supported by a gas cushion. Actual values of the surface temperatures associated with a respective substrate-retaining element are successively measured and the surface temperatures are controlled in a closed-loop manner to a common value by varying the gas cushion height. After measuring each actual value of the surface temperature associated with a substrate-retaining element and using only the respective last-measured actual value of the surface temperatures of each substrate-retaining element, a first average value is calculated, a difference value associated with the substrate-retaining element is calculated, and an approximate actual value is calculated for each of the other substrate-retaining elements by adding the associated difference value to the first average value, said approximate actual value being used for the open-loop/closed-loop control.
