  • Patent number: 8690135
    Abstract: There is provided a chuck that includes a supporting element that is connected to a closing element. An upper surface of the supporting element includes a chemically etched zone and an un-etched zone. The chemically etched zone includes multiple upper areas that are surrounded by trenches. At least one pressurized gas conduit is formed in the supporting element so as to enable pressurized gas provided to a lower surface of the supporting element to propagate through the trenches. The un-etched zone is shaped in response to a shape of an object to be placed on the supporting element. The un-etched zone reduces pressurized gas leakage from the un-etched zone and the closing element reduces pressurized gas leakage from a lower surface of the supporting element when the object is placed on the chuck in alignment with the un-etched zone and pressurized gas is provided to the chuck.

  • Patent number: 8573077
    Abstract: A method for inspecting a wafer and a system. The system includes: a chuck; and a robot that includes a movable element connected to a detachable adaptor selected from a group of diced wafer detachable adaptors and non-diced wafer detachable adaptors; wherein a diced wafer detachable adaptor is shaped such to partially surround the diced wafer and comprises at least one vacuum groove adapted to apply vacuum on a tape that supports the diced wafer; and wherein the robot is adapted to fetch the wafer from a cassette and to place the wafer on the chuck.
