Method of forming a patterned polymer layer
View Patent ↗A method of producing a patterned polymeric insulator includes providing a substrate. A patterned polymeric inhibitor is provided on the substrate. An inorganic thin film is deposited using an atomic layer deposition process on the substrate in an area where the patterned polymeric inhibitor is absent. A material layer is deposited over the inorganic thin film and the patterned polymeric inhibitor.
1. A method of forming a multilayer dielectric stack comprising:
providing a substrate;
providing a patterned polymeric inhibitor on the substrate;
depositing an inorganic thin film using an atomic layer deposition process on the substrate in an area where the patterned polymeric inhibitor is absent; and
forming the multilayer dielectric stack by depositing an inorganic dielectric material layer over the inorganic thin film and the patterned polymeric inhibitor, wherein the inorganic dielectric material layer and the patterned polymeric inhibitor are each layers in the multilayer dielectric stack.
2. The method of claim 1 , wherein providing a patterned polymeric inhibitor on the substrate includes using a printing process.
3. The method of claim 1 , wherein providing a patterned polymeric inhibitor on the substrate includes using a photolithographic process.
4. The method of claim 1 , further comprising treating the patterned polymeric inhibitor prior to depositing the inorganic dielectric material layer over the inorganic thin film and the patterned polymeric inhibitor.
5. The method of claim 4 , wherein treating the patterned polymeric inhibitor includes using an oxygen plasma process or a UV ozone process.
6. The method of claim 1 , wherein depositing the inorganic dielectric material layer includes using an atomic layer deposition process.
7. The method of claim 6 , wherein depositing the inorganic dielectric material layer includes using a selective area deposition process to pattern the inorganic dielectric material layer during the atomic layer deposition process.
8. The method of claim 1 , further comprising depositing a polymeric thin film over the inorganic thin film and the patterned polymeric inhibitor prior to depositing the inorganic dielectric material layer, wherein the polymeric thin film is another layer in the multilayer dielectric stack.
9. The method of claim 8 , wherein depositing the polymeric thin film includes using a coating or a printing process.
