The valve features a novel sealing technology that enhances the unit’s functionality while eliminating the need for additional gasket seals. Shaft seals incorporate a double O-ring to protect against external leakage. A disk seal replaces the traditional rubber liner to allow the disk to completely disengage from the disk seal during valve opening. (Semicon West, South Hall, Booth 1438)

Photolithography Mask Aligners


Morgan Hill, CA

Custom-engineered and remanufactured Canon PLA 501/600 and MPA 600-series mask aligners are used in a range of applications, including MEMS and LEDs. The first step in the remanufacturing process involves dismantling the mask aligner down to the component level. Salvageable parts, such as castings and guideshaft components, are cleaned and reprocessed. Then all consumable items are replaced with new or remachined parts. Most of the optics also undergo replacement. In-house engineers then customize the tools to customer specifications. Requirements that go beyond the tools’ normal design capability can be met. Tools are upgraded with more functionality than they had when they were new. Features such as infrared backside alignment can be engineered into the refurbished systems, enabling them to be used in the MEMS environment. The systems can also be adapted to handle substrates with new shapes and sizes, such as squares and rectangles. (Semicon West, South Hall, Booth 405)
