Patent ID: 7968270

Claim:
A lithographic structure consisting essentially of: an organic antireflective material disposed on a substrate; a vapor-deposited RCHX material disposed on the organic antireflective material, wherein R is one or more elements selected from the group consisting of Si, Ge, B, Sn, Fe and Ti, and wherein X is not present or is one or more elements selected from the group consisting of O, N, S and F; and a photoresist material disposed on the RCHX material, wherein the RCHX material has a thickness of T and the organic antireflective material has a thickness of about 4T to about 12T, and wherein the organic antireflective material is selected from the group consisting of poly(3-hydroxystyrene), poly(acrylic acid), poly(norbonene carboxylic acid), copolymer of (4-hydroxystyrene and styrene), copolymer of 4-hydroxystyrene and acrylic acid, copolymer of styrene and acrylic acid, and copolymer of norbonene and maleic anhydride.
