    摘要: Methods for preparing semiconductor wafers are disclosed. A method includes rotating a semiconductor wafer in a vertical orientation, and the wafer having first and second opposing surfaces. The method further includes contacting each of the first and second opposing surfaces of the wafer with a cylindrical wafer preparation member so as to define a substantially linear contact area. The cylindrical wafer preparation members are disposed in an opposing relationship such that the contact areas are defined at corresponding locations on the first and second opposing surfaces. Then, the method includes controlling at least one wafer preparation parameter to obtain a variable wafer material removal rate as the contact areas defined on the first and second opposing surfaces are moved from a first position to a second position. The variable wafer material removal rate being formulated to provide the wafer with a substantially uniform thickness.

    摘要: A substrate polishing system includes two hollow drums and motors for driving the drums in a reciprocating manner. An abrasive tape wound on supply and takeup rollers is introduced, with the supply roller mounted inside one of the drums and the takeup roller mounted inside the other drum. The abrasive tape exits the interior of each drum through a slot in the surface of the drum. Between the drums the abrasive tape passes over a platen having a bearing surface. A substrate is mounted in a carrier and forced against the abrasive tape where it overlies the bearing surface. The drums are rotated reciprocally, thereby causing the abrasive tape to move back and forth over the platen and polishing the substrate. After a substrate has been polished the tape is advanced a selected distance by indexing motors that are connected to the supply and takeup rollers. After several substrates have been polished, each successive substrate is exposed to a section of the abrasive tape that has experienced the same amount of wear. Thus the uniformity of polishing between substrates is improved. Also, the use of the drums allows the tape to reach a desired speed in order to polish the substrate in a minimal period of time. Abrasive tape conditioners are positioned on the sides of the carrier. Because the tape moves back and forth under the conditioners, rather than only in a single direction, the cleaning of the tape is improved. In an alternative embodiment the tape is not abrasive and instead an abrasive slurry is applied to the tape.

    摘要: A method and apparatus for cleaning a wafer oriented vertically is provided. The apparatus includes a first brush and a second brush located horizontally from the first brush. During use, a wafer is orientated vertically between the first and second brushes. The brushes are brought into contact with the wafer and rotated thereby engaging the wafer with rollers. By rotating the rollers, the wafer is also rotated. Liquid is sprayed towards the brushes and wafer. By orienting the wafer vertically, liquid and particulates contained therein readily fall from the wafer due to gravity. This is particularly advantageous when cleaning larger diameter wafers in which particulates must be removed from a larger wafer surface area.

    摘要: In a spin dryer for semiconductor wafers, the wafer is held beneath a platen with its active side (i.e., the side containing the components or circuitry) facing upward. One or more nozzles spray rinse water on the top surface of the wafer and the wafer is rotated to remove the excess rinse water, thereby drying the wafer. A splash guard adjacent the edge of the wafer insures that the excess rinse water thrown off by the spinning wafer is deflected downward where it cannot again come into contact with the active side of the wafer. The platen is rotated dry at the same time, with no rinse water being splashed back onto the active side of the wafer. The spin dryer also includes a separate section which cleans and dries the end-effector of the robot which inserts the wafer into the spin dryer while the wafer is being dried.

    摘要: A method and apparatus for cleaning a wafer oriented vertically is provided. The apparatus includes a first brush and a second brush located horizontally from the first brush. During unloading of the wafer after cleaning, the wafer is located vertically between the first and second brushes and on a pair of rollers. A finger tip located vertically above the region between the first and second brushes contacts an edge of the wafer and thus hold the wafer in the precise unloading position at which a wafer transfer robotic arm has been programmed to engage/disengage the wafer. Accordingly, the wafer is reliably and repeatedly engaged by the robotic arm.
