Abstract:
A compositionally-graded thin film is formed on a substrate by atomic layer deposition. A mixing system provides a homogeneous gaseous mixture having a controllable ratio of first and second reactive gaseous species. The first and second reactive gaseous species each react with a third reactive gaseous species but do not react with each other. A deposition unit includes first and second reactive gas zones. The homogeneous gaseous mixture is provided to the first reactive gas zone, and the third reactive gaseous species is provided to the second reactive gas zone. The mixing system is controlled to change the ratio of the first and second reactive gaseous species as a function of time as the substrate is moved relative to the deposition unit such that the deposited material has a variable composition as a function of height above the substrate.

Claim (Index 1):
A process of making a compositionally-graded thin film comprising:\n providing a substrate having a substrate surface; providing a spatial atomic layer deposition system having a deposition unit, wherein the deposition unit includes a first reactive gas zone and a second reactive gas zone; providing a mixing system to mix a controllable ratio of a first reactive gaseous species and a second reactive gaseous species to provide a first reactive gaseous material; supplying the first reactive gaseous material to the first reactive gas zone of the deposition unit; supplying a second reactive gaseous material including a third reactive gaseous species to the second reactive gas zone of the deposition unit; wherein the first reactive gaseous species and the second reactive gaseous species are each capable of reacting with the second reactive gaseous material but do not react with each other under a specified set of operating conditions; causing a relative motion between the deposition unit and the substrate according to a specified motion profile to cause the substrate surface to be sequentially exposed to the first and second reactive gaseous materials in the first and second reactive gas zones, respectively, thereby depositing material on the substrate; and controlling the mixing system to vary the ratio of the first and second reactive gaseous species during the relative motion such that the combination of the controlling the mixing system and the motion profile causes the deposition of a compositionally-graded thin film having a variable composition as a function of height above the substrate surface.
