Abstract:
An apparatus for depositing a material by evaporation on a substrate, comprising:an enclosure having at least one internal wall dividing said enclosure into at least two enclosure compartments; an evaporation source in each said enclosure compartments of said enclosure, and a substrate holder positioned to hold a substrate at a side of said enclosure such that the substrate is simultaneously exposed to vapor from more than one of said enclosure compartments, wherein said substrate holder is positioned to hold the substrate such that said at least one internal wall intercepts a portion of a first vapor from a first one of said vapor sources thereby substantially preventing said portion of said first vapor from reaching a second portion of the substrate, and wherein said at least one internal wall intercepts a portion of a second vapor from the second one of said vapor sources thereby substantially preventing said portion of said second vapor from reaching a first portion of the substrate.
