ABSTRACT:
The invention relates to a method for controlling the surface temperatures of substrates arranged on substrate supports borne by a substrate support carrier on dynamic gas cushions in a processing chamber of a CVD-reactor. The aim of the invention is to reduce or adjust the temperature variations. According to the invention, an average surface temperature value is calculated, being measured in a particularly optical manner, and the level of the gas cushions is regulated by varying the individually controlled gas flow producing the gas cushions in such a way that the variations of the measured surface temperatures in relation to the average value lies within a predetermined temperature window.
