Abstract: Compositions for directed self-assembly patterning techniques are provided which avoid the need for separate anti-reflective coatings and brush neutral layers in the process. Methods for directed self-assembly are also provided in which a self-assembling material, such as a directed self-assembly block copolymer, can be applied directly to the silicon hardmask neutral layer and then self-assembled to form the desired pattern. Directed self-assembly patterned structures are also disclosed herein.

Abstract: A portable ski clamping apparatus is described for rigidly supporting a ski for maintenance and repairs. The apparatus includes a base from which a ski is to be supported, a clamp projecting centrally from the base adapted to grip a ski by its side edges generally at the mid-portion of such ski, a pair of support standards projecting from the base on opposite sides of the clamp to be engaged by a ski gripped by the clamp, and means for reducing the distance of the clamp from the base relative to the distance therefrom at which the support standards engage the ski to thereby urge the ski against such support standards for lateral support at the locations of such standards. The standards define open-mouthed slots which are generally parallel to one another for simultaneous receipt of a ski on edge at spaced-apart locations.
