  • Patent number: 6876191
    Abstract: An apparatus for treating wafers, provided with at least one treatment chamber, the apparatus being provided with a feeding section in which wafers contained in a wafer storage box can be fed into the apparatus, the apparatus being provided with a wafer handling apparatus, by means of which wafers can be taken out of the wafer storage boxes so as to be treated in the treatment chamber, and the apparatus being provided with at least one sensor box arranged such that the wafer handling apparatus can feed a wafer into the sensor box through an opening provided for that purpose in the at least one sensor box, and the at least one sensor box being arranged to carry out measurements at a wafer, wherein the at least one sensor box is movably arranged and the apparatus is provided with a sensor box handling apparatus arranged to move the at least one sensor box from a storage position to a measuring position.
    Type: Grant
    Filed: February 24, 2003
    Date of Patent: April 5, 2005
    Assignee: ASM International N.V.

  • Patent number: 6561798
    Abstract: An apparatus for thermally processing a wafer at an elevated temperature, in which a processing position is bounded at least on one side by a housing part which, in use, is at an elevated temperature, the apparatus being provided with measuring means for determining the position of a wafer in the processing position before and/or during processing, the measuring means being provided with at least one signal processor and at least one signal conductor, the or each signal processor being located at a distance from the processing position in an area of lower temperature, the signal conductor extending through the housing part being at an elevated temperature and extending from a measuring point in or near the processing position to the signal processor for transmitting to the signal processor contactlessly obtained measuring signals, the at least one signal conductor, at least the part extending through the housing part being at an elevated temperature, being heat resistant.

  • Patent number: 6551404
    Abstract: An apparatus for treating a wafer manufactured from semiconducting material, the apparatus comprising a first and a second housing part arranged for movement away front and towards each other, the two housing parts bounding a treatment chamber, while around the treatment chamber there is provided a first groove connected to gas discharge means, while in at least one of the two boundary surfaces there is provided a second groove connected to gas feed means, the first groove being located radially within the second groove, and, in use, the pressure created by the gas feed means being such that from the second groove, gas flows both in radial inward and in radial outward direction in the gap between the first and the second boundary surface.
