Patent ID: 8192642

Claim:
A method of forming a microelectronic device, said method comprising contacting a microelectronic structure with an etchant selected from the group consisting of basic etchants and acidic etchants, said microelectronic structure comprising: a microelectronic substrate having a surface; a primer layer adjacent said substrate surface; and a first protective layer adjacent said primer layer, said first protective layer being formed from a composition comprising a first polymer and a compatible compound dissolved or dispersed in a solvent system, wherein: said first polymer comprises: wherein: each R 1 is individually selected from the group consisting of hydrogen and C 1 -C 8 alkyls; and each R 2 is individually selected from the group consisting of hydrogen, C 1 -C 8 alkyls, and C 1 -C 8 alkoxys; said compatible compound is selected from the group consisting of: monomers, oligomers, and polymers comprising epoxy groups; poly(styrene-co-allyl alcohol); and mixtures thereof; and said composition is substantially free of photoacid generators.
