Abstract

See full text

An apparatus for thermally treating semiconductor substrates has a processing space which is defined by first walls substantially parallel to the semiconductor substrate and a second side wall connected to the first walls; a substrate holding device disposed in the processing space which defines a substrate retaining region for a semiconductor substrate in the processing space; and heating elements which are disposed in the processing space between at least one of the first walls and the substrate retaining region. The thermal gradient between the edge of the semiconductor substrate and the center of the semiconductor substrate can be effectively compensated by providing a shutter between the substrate retaining region and the heating elements which limits the radiation emitted in the processing space by the heating elements in the direction of the substrate retaining region.
