Selective coating of a structure
A method of coating a structure is disclosed. Method steps include providing a structure having a first portion of a first material having a first surface and providing a second portion of a second material having a second surface, wherein a mask is provided over the first surface. Another step includes exposing the mask and the second surface to a solution comprising a polymer and a solvent, wherein the solution dewets from the mask and the polymer collects onto the second surface to form a polymer coating over the second surface without forming a polymer coating on the first surface.
