    摘要: Disclosed is a structure made of a trench patterned substrate having a pre-determined trench period and a pre-determined mesa to trench width ratio, and a block copolymer on top of the trench patterned substrate. The block copolymer has at least an organic block and a silicon-containing block, wherein the block copolymer can have either perpendicular or parallel cylinders. The structure is annealed under a pre-determined vapor pressure for a predetermined annealing time period, wherein the pre-determined trench period, the pre-determined mesa to trench width ratio, the predetermined vapor pressure and the predetermined annealing time period are chosen such that cylinders formed in the block copolymer are either perpendicular or parallel with respect to the trench-patterned substrate. A method is also described to form the above-mentioned structure.

    摘要: Complex self-assembled patterns can be created using a sparse template and local changes to the shape or distribution of the posts of the template to direct pattern generation of block copolymer. The post spacing in the template is formed commensurate with the equilibrium periodicity of the block copolymer, which controls the orientation of the linear features. Further, the posts can be arranged such that the template occupies only a few percent of the area of the final self-assembled patterns. Local aperiodic features can be introduced by changing the period or motif of the lattice or by adding guiding posts. According to one embodiment, an array of carefully spaced and shaped posts, prepared by electron-beam patterning of an inorganic resist, can be used to template complex patterns in a cylindrical-morphology block copolymer. These complex self-assembled patterns can form a mask used in fabrication processes of arbitrary structures such as interconnect layouts.

    摘要: A magnetic disk storage medium (10) includes a smooth non-magnetic substrate (11) having surface roughened by sputter-depositing a continuous nonmagnetic rough thin film ("texture film") (14) over the substrate. The sputter conditions and composition of the texture film (14) are chosen to give a desired roughness and areal density of asperities. A sputtered adhesion layer (12) and/or a sputtered capping layer (15) are included to control the growth of the texture film and to improve its mechanical properties, respectively. A non-magnetic underlayer, a magnetic layer and a protective layer are then sputtered sequentially over the roughened substrate.

    摘要: The present invention relates to the self-assembly of a spherical-morphology block copolymer into V-shaped grooves of a substrate. Although spherical morphology block copolymers typically form a body-centered cubic system (bcc) sphere array in bulk, the V-shaped grooves promote the formation of a face-centered cubic system (fcc) sphere array that is well ordered. In one embodiment, the (111) planes of the fcc sphere array are parallel to the angled side walls of the V-shaped groove. The (100) plane of the fcc sphere array is parallel to the top surface of the substrate, and may show a square symmetry among adjacent spheres. This square symmetry is unlike the hexagonal symmetry seen in monolayers of spherical domains and is a useful geometry for lithography applications, especially those used in semiconductor applications.
