Patent ID: 8084185

Claim:
A photolithography method comprising: forming a planarization layer of a planarization composition on a substrate, wherein said planarization composition comprises at least one aromatic monomer and at least one non-aromatic monomer and said at least one aromatic monomer has a weight concentration ranging from about 5% to about 35% of the total weight of said planarization composition; bringing a substantially flat surface into contact with said planarization layer on said substrate; curing said planarization layer by exposing said planarization layer to a first radiation or by baking said planarization layer; removing said substantially flat surface; forming a photoresist layer on said planarization layer; exposing said photoresist layer to a second radiation having an imaging wavelength; developing said photoresist layer to form a relief image in said photoresist layer; and transferring said relief image into said substrate.
