Abstract:
1. A method of forming a microelectronic structure, said method comprising: (a) providing a substrate having a surface; (b) applying a photosensitive composition to form an imaging layer adjacent said substrate surface, said composition comprising a component selected from the group consisting of polymers, oligomers, and monomers; (c) crosslinking said component in said imaging layer to yield a crosslinked imaging layer, said crosslinked imaging layer having a k value of from about 0.2 to about 0.5; (d) exposing said crosslinked imaging layer to light to yield light-exposed portions in said layer; (e) contacting said layer with a developer so as to remove said light-exposed portions from said substrate, yielding a patterned imaging layer; and without heating said patterned imaging layer, applying a second photosensitive composition to form a second imaging layer on said patterned imaging layer.
