Abstract

A susceptor for a CVD-reactor includes insertion openings arranged in a bearing surface of the susceptor. An insertion section of a positioning element is inserted into one of the insertion openings. The insertion section forms positioning flanks with a section projecting from the insertion opening for fixing the position of a substrate. The insertion openings each have side walls and a base. The insertion section comprises bearing areas adjacent to the side walls of the insertion openings and a lower side of the positioning element facing the base of the insertion opening. The base of the insertion opening is separated from the lower side of the positioning element by a first distance. An edge protruding section of the positioning element is separated from a section of the bearing surface of the susceptor by a second distance.
