Patent ID: 8852848

Claim:
An aqueous composition for coating over a photoresist pattern comprising a first water soluble compound comprising at least a silicon moiety and at least one amino group, and a second compound comprising at least 2 carboxylic acid group where the composition is capable of forming a conformal attached layer to the photoresist in which the amino groups of the conformal layer reacts with the surface of the photoresist to form an interface attached layer which is insoluble in an aqueous removing solution and further were the photoresist pattern contains groups chosen from the group comprising carboxylic acid, lactones, anhydrides and esters, and further were the unreacted, portion of the coating is removed with the aqueous removing solution and further wherein the first compound comprises an oligomer or polymer of siloxane (Si—O) or silane (Si—Si) moieties which further comprise a functional group of structure 1, where R 1 is selected from hydrogen, C 1 -C 8 alkyl, and C 1 -C 6 carbonylalkyl, R 2 is selected from C 1 -C 12 aliphatic alkylene, C 1 -C 12 carbonylaliphatic alkylene, C 1 -C 12 carbonylaminoaliphatic alkylene and C 1 -C 12 aminoaliphatic alkylene and is the point of attachment to the residual portion of the first compound.
