Patent ID: 8491987

Claim:
A coated substrate, comprising: a substrate, wherein the substrate comprises a first set of regions having first chemical characteristics and a second set of regions having second chemical characteristics different from the first chemical characteristics; a surface modifying material disposed on the substrate; a first polymer on the surface modifying material, and having an affinity for the first set of regions; and a second polymer on the surface modifying material, and having an affinity for the second set of regions, wherein the first polymer is selected from the group consisting of poly(vinyl imidazoles), polyphosphazenes, polythiophenes, polyimines, polyheterocyclics, polyimides, polyoxazoles, polybenzoxazoles, polythiazoles, polypyazole, polytriazole and polythiophene, wherein the second polymer is selected from the group consisting of poly(vinyl pyridines, poly(vinyl imidazoles), poly(glycols), polycarbonates, polyalkyls, polyureas, polyurethanes, polyethers, polysulfones, polythioethers, polyoxazoles, polyimides, polyheterocyclics, polysilicones and polysilanes, and wherein the substrate is selected from the group consisting of a silicon wafer, a ceramic chip carrier, an organic chip carrier, a semiconductor wafer, and a circuit board.
