  • Patent number: 6386213
    Abstract: A plate-tilting apparatus adapted to be used in a semiconductor-manufacturing process is disclosed. The plate-tilting apparatus is used for preventing thin wafers from being collected in a cassette contacted with each other after the thin wafers are taken out of a solution. It includes a plate having the container locked thereon and having a first edge pivotally connected to a basal plane of a tank used in the semiconductor-manufacturing process, and a plate-lifting device connected to a second edge of the plate opposite to the first edge for lifting the second edge of the plate, so that the plate can be tilted at a specific angle.
