Bonded Slit Valve Door Technology
The Bonded Slit Valve Door (BSV) increases the life expectancy and performance of the door's seal during semiconductor processing. Made from Greene Tweed's proprietary perfluoroelastomer compound, Chemraz® (or other customer requested elastomers), the seal is bonded to an aluminum/stainless steel door. Installation requires only removing and replacing a few bolts when replacing the complete BSV door assembly as opposed to cleaning the gland and installing a new o-ring. A bonded design minimizes abrasion, leading to less particulation in many processes compared to installation of a typical perfluoroelastomer o-ring. Therefore, a bonded-gate design can eliminate installation errors and variations, reduce particle generation caused by o-ring movement in the gland, and provide up to a 10-fold increase in service life.
