  • Publication number: 20230287569
    Abstract: An apparatus for depositing a layer of semiconductor material on a substrate wafer. The apparatus includes a base ring between an upper and a lower dome, a susceptor as carrier of the substrate wafer during the deposition of the layer, a gas inlet and a gas outlet, an outgoing gas line and gas supply lines for passing process gas over an upper side face of the substrate wafer, a slit valve tunnel and a slit valve door, and a lifting and rotating unit for lifting and turning the susceptor and the substrate wafer. The apparatus also including an amorphous layer including silicon and hydrogen disposed over one or more stainless steel components of the apparatus.

  • Publication number: 20230178398
    Abstract: A method and an apparatus for depositing an epitaxial layer on a substrate wafer made of semiconductor material. The method comprises the arrangement of the substrate wafer and a susceptor in a deposition device such that the substrate wafer rests on the susceptor and the susceptor is held by arms of a support shaft; monitoring whether a misalignment of the susceptor exists with respect to its position relative to the position of a pre-heating ring surrounding it; monitoring whether a misalignment of the support shaft exists with respect to its position relative to the position of the pre-heating ring; if at least one of the misalignments is present, elimination of the respective misalignment; and the deposition of the epitaxial layer on the substrate wafer.

  • Patent number: 11302565
    Abstract: A device for handling a semiconductor wafer in an epitaxy reactor has a susceptor; longitudinal holes extending through the susceptor; a wafer lifting shaft; wafer lifting pins guided through the longitudinal holes; a susceptor carrying shaft; susceptor carrying arms; susceptor support pins; guide sleeves anchored in the susceptor carrying arms; and guide elements protruding from the guide sleeves which, at upper ends, have bores into which wafer lifting pins are inserted, and which can be raised and lowered together with the wafer lifting pins by the wafer lifting shaft.
