Abstract:
A method of fabricating a thin film of solid material in an integrated circuit, comprising steps of:providing a substrate having a first substrate surface and a second substrate surface, said first substrate surface having at least one physical property that is different than the corresponding physical property of said second substrate surface; selecting a precursor liquid and a precursor liquid deposition process such that applying said precursor liquid to said first and second substrate surfaces using said liquid deposition process will form a solid thin film on said first substrate surface upon treating of said liquid precursor and will not form a solid thin film on said second substrate surface upon treating of said liquid precursor: applying a thin film of said precursor liquid to said substrate using said liquid deposition process to coat said substrate; and treating said coating on said substrate to form said thin film of solid material on said first substrate surface; wherein said first and second substrate surfaces become part of said integrated circuit.
