Patent ID: 7084445

Claim:
A shutter mask system for use in a substrate processing chamber, the shutter mask system comprising: (A) a flange adapted for coupling said mask system to said processing chamber, wherein mounted to said flange are: (1) a pedestal for mounting said substrate relative to said processing chamber; (2) at least two physical masks, said masks being movably mounted to the flange and positioned to form at least one opening to allow delivery of components through such opening(s) onto said substrate on said pedestal; and (3) a substrate heater system mounted on said flange adjacent to said pedestal; and (B) at least one drive for moving the physical masks in one or more directions to vary at least one of a size, shape and position of the opening relative to the substrate and for generating in a combinatorial fashion an array of resulting materials having composition gradients on said substrate; and (C) a control system coupled to said drives for controlling movement of the physical masks during deposition and forming an array of resulting materials on the substrate that differ in composition.
