Patent ID: 7582896

Claim:
A method of producing a dielectric layer for an organic field effect transistor (OFET), the method comprising: providing a substrate having a prestructured gate electrode; applying a polymer formulation on the substrate, wherein the polymer formulation comprises: a. about 100 parts of at least one crosslinkable base polymer, b. from about 10 to about 20 parts of at least one di- or tribenzyl alcohol compound as an electrophilic crosslinking component, c. from about 0.2 to about 10 parts of at least one photo acid generator; and d. at least one solvent, effecting a photoinduced crosslinking reaction after applying the polymer formulation; performing a post exposure bake after effecting the photoinduced crosslinking reaction; and applying a source-drain layer to the dielectric layer after performing post exposure bake.
