摘要:
A template is treated to provide a surfactant rich region and a surfactant depleted region. A contact angle at the surfactant rich region may be greater than, less than, or substantially similar to a contact angle of the surfactant depleted region.

Densifying a multi-layer substrate includes providing a substrate with a first dielectric layer on a surface of the substrate. The first dielectric layer includes a multiplicity of pores. Water is introduced into the pores of the first dielectric layer to form a water-containing dielectric layer. A second dielectric layer is provided on the surface of the water-containing first dielectric layer. The first and second dielectric layers are annealed at temperature of 600° C. or less. In an example, the multi-layer substrate is a nanoimprint lithography template. The second dielectric layer may have a density and therefore an etch rate similar to that of thermal oxide, yet may still be porous enough to allow more rapid diffusion of helium than a thermal oxide layer.

A micro-conformal nanoimprint lithography template includes a backing layer and a nanopatterned layer adhered to the backing layer. The elastic modulus of the backing layer exceeds the elastic modulus of the nanopatterned layer. The micro-conformal nanoimprint lithography template can be used to form a patterned layer from an imprint resist on a substrate, the substrate having a micron-scale defect, such that an excluded distance from an exterior surface of the micron-scale defect to the patterned layer formed by the nanoimprint lithography template is less than a height of the defect. The nanoimprint lithography template can be used to form multiple imprints with no reduction in feature fidelity.

The present invention includes a composition for a silicon-containing material used as an etch mask for underlying layers. More specifically, the silicon-containing material may be used as an etch mask for a patterned imprinted layer comprising protrusions and recessions. To that end, in one embodiment of the present invention, the composition includes a hydroxyl-functional silicone component, a cross-linking component, a catalyst component, and a solvent. This composition allows the silicon-containing material to selectively etch the protrusions and the segments of the patterned imprinting layer in superimposition therewith, while minimizing the etching of the segments in superposition with the recessions, and therefore allowing an in-situ hardened mask to be created by the silicon-containing material, with the hardened mask and the patterned imprinting layer forming a substantially planarized profile.

摘要:
Porous nano-imprint lithography templates may include pores, channels, or porous layers arranged to allow evacuation of gas trapped between a nano-imprint lithography template and substrate. The pores or channels may be formed by etch or other processes. Gaskets may be formed on an nano-imprint lithography template to restrict flow of polymerizable material during nano-imprint lithography processes.

An imprint lithography mold assembly includes a mold having a surface, a substrate having a surface, and a polymerizable composition disposed between the surface of the mold and the surface of the substrate. The polymerizable composition includes a bulk material and a non-ionic surfactant having a first end and a second end. The first end of the non-ionic surfactant has an affinity for the bulk material, and the second end of the non-ionic surfactant is fluorinated.

Methods for manufacturing a patterned surface on a substrate are described. Generally, the patterned surface is defined by a residual layer having a thickness of less than approximately 5 nm.
摘要:
The present invention provides a method and composition for providing preferential adhesion and release of adjacent surfaces, that features solidifying a composition to form a solidified layer having first and second opposed sides, with the first side facing a first surface and being adhered thereto with a first adhesive forces and the second side facing the second surface and being adhered thereto with a second adhesive force, with the first and second adhesive forces establishing a predetermined preferential adhesion ratio. Generally, the first surface is covalently bonded to the first side and adhesion between the second side and the second surface occurs through Van der Waal forces. It has been found that the use of a fluorine group for enhancing the release properties (as a priori fluorinated release layer or a fluorinated release agent) is no longer needed for such method and composition. In one embodiment, the composition can be formed from an isobornyl acrylate component; an aliphatic urethane acrylate component; a 1,6-hexanediol diacrylate component; and a 2-hydroxy-2-methyl-1-phenyl-propan-1-one component. The first surface can be formed by polymerizing a compound formed from a multi-functional component that contains functional groups facilitating the formation of covalent bonds with the above mentioned polymerizable composition during an imprinting process, a cross-linking agent component, a catalyst component, and a solvent component. The second surface is usually a patterned or smoothed portion of a quartz mold.
