Abstract (en)

[origin: DE19919902A1] The invention relates to a method for producing a wafer support with a coating, applied after the cleaning of said wafer support which has been specially pre-fabricated by mechanical means. Said coating is produced by heating the cleaned wafer support to high temperatures, applying coating components for converting the surface of the wafer support into a protective layer, or for facilitating the deposition of the supplied components, in order for them to form a protective layer. The invention is characterised in that the inventive wafer support, comprising said special coating, can be used in a system and a method for high-temperature CVD processing, using aggressive gases in such a way, that in addition to the desired sequence of layers being reducibly deposited with a very high degree of uniformity in the material characteristics, there is no chemical interaction with the wafer support.
