Abstract
A deposition system includes a system housing having a housing interior, a fixture transfer assembly having a generally sloped fixture transfer rail extending through the housing interior, a plurality of sequentially ordered deposition chambers connected by the fixture transfer rail, a controller interfacing with the processing chambers and at least one fixture carrier assembly carried by the fixture transfer rail and adapted to contain at least one substrate. The fixture carrier assembly travels along the fixture transfer rail under influence of gravity. A substrate fixture contains a substrate. The substrate fixture comprises a fixture frame. The fixture frame is defined by multiple circular members adjacently joined in a circular arrangement. Each circular member has a fixture frame opening sized to receive the substrate. Lens support arms may integrate into the circular members, extending in a curved disposition into the fixture frame opening to retain the substrate. A deposition method is also disclosed.
