Abstract:
1. A method for forming a photoresist relief image comprising: (a) applying over a substrate a coating layer of a composition comprising a component that comprises 1) a hydroxyl-naphthoic group and 2) a reaction product of an imide-containing dienophile and a polycyclic aromatic group; (b) applying a photoresist layer above the coating composition layer; and (c) exposing the applied photoresist layer to patterned radiation and then developing the exposed photoresist layer with an aqueous alkaline developer composition, wherein the developer selectively removes both the photoresist layer and the underlying coating composition layer the image as defined in the photoresist layer by patterned activating radiation.
