Abstract:
1. A method of producing a patterned inorganic thin film dielectric stack comprising: providing a substrate; providing a first patterned deposition inhibiting material layer on the substrate; selectively depositing a first inorganic thin film dielectric material layer on a region of the substrate where the first deposition inhibiting material layer is not present using an atomic layer deposition process within an atomic layer deposition (ALD) system; forming an interface region on the first inorganic thin film dielectric layer prior to selectively depositing a second inorganic thin film dielectric material layer region on the first inorganic thin film dielectric layer by simultaneously treating the first deposition inhibiting material layer and the first inorganic thin film dielectric material layer after the deposition of the first inorganic thin film dielectric material layer by at least removing the substrate from the ALD system to a different environmental condition than that experienced in the ALD system; providing a second patterned deposition inhibiting material layer on the substrate; and selectively depositing a second inorganic thin film dielectric material layer on a region of the substrate where the second deposition inhibiting material layer is not present using an atomic layer deposition process within the ALD system, the first inorganic thin film dielectric material layer and the second inorganic thin film dielectric material layer forming a patterned inorganic thin film dielectric stack, wherein the first inorganic thin film dielectric material layer and the second inorganic thin film dielectric material layer have the same material composition.
