Patent ID: 8273519

Claim:
A hardmask composition, comprising: a solvent; an organosilicon copolymer including a UV chromophore group X, the organosilicon copolymer is represented by Formula C: (SiO 1.5 —Y—SiO 1.5 ) x (R 3 SiO 1.5 ) y (XSiO 1.5 ) z (C); and about 0.0001 parts by weight to about 0.01 parts by weight, based on 100 parts by weight of the organosilicon copolymer, of one or more of pyridinium p-toluenesulfonate, amidosulfobetain-16, (−)-camphor-10-sulfonic acid ammonium salt, ammonium formate, triethylammonium formate, trimethylammonium formate, tetramethylammonium formate, pyridinium formate, tetrabutylammonium formate, tetramethylammonium nitrate, or tetrabutylammonium nitrate, wherein, in Formula C: x, y and z satisfy the following relations: x is about 0.05 to about 0.9, y is about 0.05 to about 0.9, z is greater than 0 and less than about 0.9, and x+y+z=1, R 3 is a C 1 -C 12 alkyl group, Y is a linking group including: a substituted or unsubstituted, linear or branched C 1 -C 20 alkyl group, a C 1 -C 20 group containing a chain that includes an aromatic ring, a heterocyclic ring, a urea group or an isocyanurate group, or a C 2 -C 20 group containing one or more multiple bonds, and X is a C 6 -C 30 group containing at least one substituted or unsubstituted aromatic ring.
