  • Publication number: 20010049065
    Abstract: A reticle having a pellicle frame and pellicle membrane is cleaned without removing or damaging the pellicle membrane. A cover encases the pellicle membrane and pellicle frame, sealing the pellicle from the external environment during a cleaning process. The cover fits around the periphery of the pellicle frame and covers the pellicle membrane. An edge of the cover in contact with the reticle forms a seal. The reticle is fastened to reticle supports on a spin chuck during the cleaning process. An anchor plate presses the cover to the reticle, maintaining the pellicle sealed from the external environment. The cover and reticle are sandwiched together between the anchor plate and spin chuck.

  • Patent number: 6286688
    Abstract: A compliant wafer comb assembly for use in transferring semiconductor wafers between wafer cassettes, wafer carriers, or other wafer holding devices. The compliant wafer comb includes a plurality of slots in which wafer(s) can be held while being transported. The slots are parallel to each other and downward sloping from one end of the comb to the other. The sloped arrangement causes a single wafer at a time to become engaged with the comb when a batch of wafers is transferred from a cassette or wafer holding device to the comb, allowing the compliant features of the comb to compensate for the misalignment of each wafer individually. The comb is coupled to a static base structure by a set of independent column springs which permit motion of the comb slots in any direction necessary to compensate for a wafer's misalignment. This permits transfer of a misaligned wafer or wafers from a cassette or other carrier to the comb without damaging the wafer(s).

  • Patent number: 6216883
    Abstract: A wafer holding hand of the present invention is constituted so that two fixed clamps (2) and one movable clamp (6) are provided on a finger (1). The movable clamp (6) is supported by a plate spring (8) via a clamp holder (7), and the plate spring (8) is fixed to the slider (9). The slider (9) is driven by an air cylinder (10). The fixed clamp (2) is hook shaped, and the movable clamp (6) is drum shaped. A wafer W is held at three points by the movable clamp (6) and the two fixed clamps (2), and a force is applied to the movable clamp (6) by the plate spring (8) so as to hold the wafer W.

  • Patent number: 6216873
    Abstract: A reticle support mechanism is disclosed in which a reticle may be quickly and easily located and removed, and which is capable of securely supporting a reticle for storage and/or transport. A preferred embodiment of the present invention includes a pair of reticle supports mounted to a door of a container, and a pair of reticle retainers mounted to a shell of the container. When the container shell is coupled with the container door, sections of the reticle support and reticle retainer engage chamfered edges of the reticle and sandwich the reticle in a secure position within the container. As a result of engaging the reticle at its chamfered edges, potentially harmful contact with the upper and lower surfaces and vertical edges of the reticle is avoided.

  • Patent number: 6206196
    Abstract: A semiconductor wafer carrier has an enclosure with a door frame defining an opening for insertion and removal of wafers, a door for closing and sealing said opening, and separately formed door guides for controlling the interface between said door and the enclosure. In a preferred embodiment, the door guides each comprise a first body and a second body connected to each other by a web. Each body includes a door contacting portion and a door frame contacting portion. The door frame contacting portion has a sloped segment configured to slidingly, progressively, and cooperatively engage the door frame to properly position the door within door frame during closure with minimal particle generation by such contact. In this preferred embodiment, the guide is configured to be attached onto a corner edge of a door. In this arrangement, as the door is inserted into the door frame in the z-direction, the first and second bodies exert centering forces as needed in the x and y directions on corner portions of the door.

  • Patent number: 6155436
    Abstract: A wafer holder assembly includes first and second main structural members from which first and second wafer-holding arms extend. The first arm is secured to the main structural members by a graphite distal retaining member. The second arm is pivotally biased to a wafer-hold position by a graphite bias member. This arrangement provides a conductive path from the wafer to the assembly for inhibiting electrical discharges from the wafer during the ion implantation process. The assembly can further include additional graphite retaining members for maintaining the structural integrity of the assembly during the extreme conditions associated with SIMOX wafer processing without the need for potentially wafer-contaminating adhesives and conventional fasteners. The wafer-contacting pins at the distal end of the arms can be formed from silicon. The silicon pins can be coated with titanium nitride to enhance electrical contact with the wafer and to provide an abrasion resistant surface.
