Abstract

A magnetic handling assembly for thin-film processing of a substrate, a system and method for assembling and disassembling a shadow mask to cover a top of a workpiece for exposure to a processing condition. The assembly may include a magnetic handling carrier and a shadow mask disposed over, and magnetically coupled to, the magnetic handling carrier to cover a top of a workpiece that is to be disposed between the shadow mask and the magnetic handling carrier when exposed to a processing condition. A system includes a first chamber with a first support to hold the shadow mask, a second support to hold a handling carrier, and an alignment system to align the shadow mask a workpiece to be disposed between the carrier and shadow mask. The first and second supports are moveable relative to each other.
