    摘要: A substrate processing apparatus having a tube, a closed liner lining the interior surface of the tube, a plurality of gas injectors to provide a gas to an inner space of the liner, and, a gas exhaust duct to remove gas from the inner space is disclosed. The liner may have a substantially cylindrical wall delimited by a liner opening at a lower end and being substantially closed for gases above the liner opening. The apparatus may have a boat constructed and arranged moveable into the inner space via the liner opening and provided with a plurality of substrate holders for holding a plurality of substrates over a substrate support length in the inner space. Each of the gas injectors may have a single exit opening at the top and the exit openings of the plurality of injectors are substantially equally divided over the substrate support length.

    摘要: A method for forming layers with silicon is disclosed. The layers may be created by positioning a substrate within a processing chamber, heating the substrate to a first temperature between 300 and 500° C. and introducing a first precursor into the processing chamber to deposit a first layer. The substrate may be heated to a second temperature between 400 and 600° C.; and, a second precursor may be introduced into the processing chamber to deposit a second layer. The first and second precursor may comprise silicon atoms and the first precursor may have more silicon atoms per molecule than the second precursor.
