摘要： A method and associated structure. A substrate is provided. The substrate has an energetically neutral corrugated surface layer. A film is formed on the corrugated surface layer. The film includes a combination of a di-block copolymer and a stiffening compound. The di-block copolymer includes lamellar microdomains of a first polymer block and lamellar microdomains of a second polymer block. The stiffening compound is dissolved within the first polymer block. At least one lamellar microdomain is removed from the film such that an oriented structure remains on the surface layer.

摘要： Methods are disclosed for forming a layered structure comprising a self-assembled material. A method comprises disposing a photoresist layer comprising a non-crosslinking, positive-tone photoresist on a surface of a substrate; optionally baking the photoresist layer; pattern-wise exposing the photoresist layer to first radiation; optionally baking the exposed photoresist layer; developing the exposed photoresist layer with an aqueous alkaline developer to form an initial patterned photoresist layer. The initial patterned photoresist layer is treated photochemically, thermally, and/or chemically to form a treated patterned photoresist layer comprising non-crosslinked treated photoresist, wherein the treated photoresist is insoluble in a given organic solvent suitable for casting a given material capable of self-assembly, and the treated photoresist is soluble in the aqueous alkaline developer and/or a second organic solvent. A solution comprising the given material capable of self-assembly dissolved in the given organic solvent is casted on the treated patterned photoresist layer, and the given organic solvent is removed. The casted given material is allowed to self-assemble while optionally heating and/or annealing the casted material, thereby forming the layered structure comprising the self-assembled material.

摘要： An electric field is applied below a resist to reduce proximity effects associated with electron beam scattering, thereby improving the resolution of features or lines written into the resist. Although the electrons in the electron beam can be very energetic (e.g., >>10 keV), it is shown that even a small electric field can reduce the number of electrons that re-enter the resist material after being scattered in the substrate, and thus reduce the energy deposited in the resist from these electrons. One advantage of this technique is that high potentials and high fields are not required. Accordingly, the methods described can be applied to existing tooling with little modification to the electron beam system.

摘要： Magnetic medium recording performance can be enhanced by irradiating a magnetic medium with ions having an acceleration voltage of between 10 keV and 100 keV to induce exchange coupling between grains of the magnetic medium. The magnetic medium is exposed to a cumulative ion dosage of between 1013 ions/cm2 and 1017 ions/cm2 using a non-patterned exposure of the magnetic medium. The ions can be selected from the group consisting of H+, He+, Ne+, Ar+, Kr+, and Xe+. Alternatively, the ions can be selected from the group consisting of Ga+, Hg+, and In+.
