Abstract:
An apparatus for simultaneously depositing independent gradients components of two or more target materials onto a substrate, the apparatus comprising:a first target material source that directs flux of a first target material towards the substrate; a second target material source that directs flux of a second material towards the substrate; and a gradient shutter system for independently blocking a first predetermined amount of the flux of the first target material and a second predetermined amount of the flux of the second target material directed towards the substrate having a first gradient shutter that blocks the flux from the first target material and a second gradient shutter that blocks the flux of the second target material in order to generate independent gradients of the first and second target materials on the substrate, the gradients of the first and second target materials intersecting, and being simultaneously deposited onto the substrate to form a homogenous resulting material.
