Abstract:
An apparatus for drying semiconductor wafers, comprising:a lower receptacle portion defining a first compartment to retain a liquid for cleansing said semiconductor wafers; an upper chamber portion joined to said lower receptacle portion, said upper chamber portion defining a second compartment, said first compartment and second compartment together defining a workspace for drying semiconductor wafers; a vapor supply for furnishing vapor to the workspace for cleansing said semiconductor wafers; an exhaust exit for discharging vapor from the work space; a cleansing liquid exhaust exit for discharging deionized water from the workspace; a device for supporting the semiconductor wafer in the first compartment; and pitch guides located within said workspace, adjacent to the semiconductor wafer, movable to a first position and a second position in a vertical direction, wherein the pitch guides are separated from the semiconductor wafer at the first position and contact the semiconductor wafer at the second position thus preventing the movement of the semiconductor wafer.
