Patent ID: 7326303

Claim:
A thin film deposition unit for depositing an evaporated material on a substrate comprising: (a) a vacuum chamber; (b) a loading station adapted to support a material to be evaporated and including means for evaporation of the material; (c) at least one fixed thin film heater element; (d) a first transport mechanism for movement of said thin film heater element to locate at least one heater element adjacent said loading station to receive thereon a layer of material evaporated thereat; (e) a stage for supporting at least one substrate thereon; (f) a second transport mechanism for moving a substrate to a multiplicity of indexed positions; (g) stationary heated mask cooperating with said stage to provide a mask adjacent to and over a substrate thereon; and (h) actuating means for said heater element to evaporate a material through said stationary heated mask and deposit upon the substrate in a pattern determined by said mask, said second transport mechanism enabling the material evaporated from said fixed thin film heater to be deposited on the substrate at the indexed positions, wherein said thin film constituting said fixed film heater has low thermal mass having rapid temperature rise in comparison with underlying said substrate, and wherein said heater elements are comprised of at least one layer of an electrically resistive material of carbon nanotubes.
