An improved composition for protecting a vehicle, building, or airplane surface that will be painted or mechanically processed. For example, certain regions of a vehicle, building, or airplane may be masked in accordance with the present disclosure to protect those regions from paint overspray. The composition produces a film which adheres well to a surface to be protected, with few or no pinholes. Additionally, the composition can absorb any oil or grease present on the surface which can eliminate the need for towels and chemical solvents that may create toxic fumes, hazardous waste, and flammable hazards. Further, the material can be removed easily from the surface after use by peeling the film layer away from the surface.

A pattern treatment method, comprising: (a) providing a semiconductor substrate comprising a patterned feature on a surface thereof; (b) applying a pattern treatment composition to the patterned feature, wherein the pattern treatment composition comprises: a block copolymer and an organic solvent, wherein the block copolymer comprises: (i) a first block comprising a first unit formed from 4-vinyl-pyridine, and (ii) a second block comprising a first unit formed from a vinyl aromatic monomer; and (c) removing residual pattern shrink composition from the substrate, leaving a coating of the block copolymer over the surface of the patterned feature, thereby providing a reduced pattern spacing as compared with a pattern spacing of the patterned feature prior to coating the pattern treatment composition. The methods find particular applicability in the manufacture of semiconductor devices for providing high resolution patterns.
