Abstract:
1. A process for manufacturing a microelectronic device, comprising; a) providing a substrate with a photoresist pattern; b) coating the photoresist pattern with an aqueous coating composition for coating a photoresist pattern, comprising a polymer comprising at least one lactam group, where the lactam group attached to the polymer has a structure (1), where R 1 is independently selected from hydrogen, C 1 -C 4 alkyl, C 1 -C 6 alkyl alcohol, hydroxy (OH), amine (NH 2 ), carboxylic acid, and amide (CONH 2 ),  represents the attachment to the polymer, m=1-6, and n=1-4, further where the lactam group is present in the polymer in the range of 16-43 mole %; c) reacting a portion of the coating material in contact with the photoresist pattern; d) removing a portion of the coating material which is not reacted with a removal solution.
