Abstract

An embodiment of the invention provides an integrated circuit having an organic field effect transistor (OFET) with a dielectric layer. The dielectric layer is prepared from a polymer formulation comprising: about 100 parts of at least one crosslinkable base polymer, from about 10 to about 20 parts of at least one di- or tribenzyl alcohol compound as an electrophilic crosslinking component, from about 0.2 to about 10 parts of at least one photo acid generator, and at least one solvent. Another embodiment provides a semiconductor fabrication method. The method comprises applying the polymer formulation to a surface of a substrate, drying the polymer formulation, crosslinking the polymer formulation after drying, and baking the polymer formulation after crosslinking.
