Patent number: 4509456Abstract: An apparatus for guiding gas through a tube reactor in low pressure chemical vapor deposition processes. The apparatus includes the tube reactor, a substrate mounting element in the interior of the tube reactor, to receive substrates in a generally parallel position with respect to each other along the substrate mounting element, a cup-shaped inner tube surrounding the substrate mounting element, a gas feed arranged within the inner tube, a gas discharge opening arranged in the inner tube at a point opposite to the gas feed, and an intermediate zone between the tube reactor and the inner tube.
