Claims
- 1. A method of manufacturing a wafer container, the method comprising:forming a container portion primarily of polycarbonate, the container portion having a door frame; forming a door primarily of polycarbonate, the door having a perimeter portion comprised of polycarbonate and sizing the door to fit within the door frame, the door insertable into the door frame in a z direction with respect to the x-y-z coordinate system, the door requiring alignment in the x and y directions to fit within the door frame; forming a plurality of door guides separate from the door and door frame of a plastic more abrasion resistant than polycarbonate; and positioning and attaching the plurality of door guides on one of the door and the door frame whereby the other of the door and door frame contacts the plurality of door guides as the door is inserted in to the door frame to properly align the door in the x and y directions.
- 2. The method of claim 1 further comprising the step of attaching the plurality of door guides to the one of the door and door frame by flexing each of the plurality of door guides to snap said plurality of door guides into place on respective door guide receiving portions.
- 3. The method of claim 1 further comprising the step of attaching the plurality of door guides to the one of the door and door frame with separate fasteners.
- 4. The method of claim 1 further comprising the step of injection molding each of the plurality of door guides of polyetheretherketone.
- 5. A wafer container comprising:a container portion comprising polycarbonate, the container portion having a door frame; a door comprising polycarbonate, the door having a perimeter portion comprised of polycarbonate, the door sized to fit within the door frame, the door insertable into the door frame in a z direction with respect to the x-y-z coordinate system, the door requiring alignment in the x and y directions to fit within the door frame; and a plurality of door guides comprised of a plastic more abrasion resistant than polycarbonate, the door guides separately formed, positioned and attached to one of the door and the door frame whereby the other of the door and door frame contacts the door guides as the door is inserted in to the door frame to properly align the door in the x and y directions.
- 6. The wafer container of claim 5 wherein each of the plurality of door guides is attached by a fastener, and the fastener is one of the group consisting of screws, pins, rivets, and bolts.
- 7. The wafer container of claim 5 wherein the plurality of door guides are comprised of polyetheretherketone (PEEK).
- 8. A wafer container comprising:a container portion having shelves for holding wafers and a door frame defining an open front; a door having a perimeter portion and sized to fit within the door frame, the door insertable into the door frame in a z direction with respect to the x-y-z coordinate system, the door requiring alignment in the x and y directions to fit within the door frame; and a plurality of door guides separately formed, positioned and attached to one of the perimeter portion of the door and the door frame whereby the other of the perimeter portion of the door and door frame contacts the door guides as the door is inserted in to the door frame to properly align the door in the x and y directions.
- 9. A method of manufacturing a wafer container, the method comprising:forming a container portion comprising a plurality of shelves for supporting wafers and comprising a door frame; forming a door sized to fit within the door frame, the door insertable into the door frame in a z direction with respect to the x-y-z coordinate system, the door requiring alignment in the x and y directions to fit within the door frame; forming a plurality of door guides separate from the forming of the door and separate from the forming of the door frame of a plastic; and positioning and attaching the plurality of door guides on one of the door and the door frame for alignment of the door in the x and y directions when the door is inserted into the door frame.
- 10. The method of claim 9 further comprising the step of selecting each of the four door guides from an array of varying sizes to permit optimal positioning of the door in the door frame.
- 11. The method of claim 9 further comprising the step of attaching four door guides to the one of the door or door frame.
