摘要:
Water-processable positive-tone photoresists comprising a water-soluble polymer, wherein the polymer contains a heat-labile functional group that renders the polymer insoluble in water or an aqueous base upon heat treatment, and an acid-labile functional group that restores said water or aqueous base solubility to the polymer upon irradiation in the presence of a water-processable photoacid generator, are described. Also described are the methods of making such polymers and photoresists.

The present invention relates to a method the synthesis and utilization of random, cross-linked, substituted polystyrene copolymers as polymeric cross-linked surface treatments (PXSTs) to control the orientation of physical features of a block copolymer deposited over the first copolymer. Such methods have many uses including multiple applications in the semiconductor industry including production of templates for nanoimprint lithography.
摘要:
In some embodiments, the present invention is directed to methods that involve the combination of step-and-flash imprint lithography (SFIL) with a multi-tier template to simultaneously pattern multiple levels of, for example, an integrated circuit device. In such embodiments, the imprinted material generally does not serve or act as a simple etch mask or photoresist, but rather serves as the insulation between levels and lines, i.e., as a functional dielectric material. After imprinting and a multiple step curing process, the imprinted pattern is filled with metal, as in dual damascene processing. Typically, the two printed levels will comprise a “via level,” which is used to make electrical contact with the previously patterned under-level, and a “wiring level.” The present invention provides for the direct patterning of functional materials, which represents a significant departure from the traditional approach to microelectronics manufacturing.

A system and method for recognition of images may include the use of alignment markers. The image recognized may be a pattern from an array, a character, a number, a shape, and/or irregular shapes. The pattern may be formed by elements in an array such as an identification marking and/or a sensor array. More particularly, the system and method relate to discriminating between images by accounting for the orientation of the image. The size and/or location of alignment markers may provide information about the orientation of an image. Information about the orientation of an image may reduce false recognitions. The system and method of image recognition may be used with identification markings, biosensors, micro-fluidic arrays, and/or optical character recognition systems.

摘要:
A system and method for the detection of analytes in a fluid, in one embodiment, includes a light source, a sensor array, sensing elements, and a detector. More particularly, the system and method relate to discriminating mixtures of analytes in a fluid. The sensor array is formed from a supporting member into which a plurality of sensing elements may be formed. The sensing element may have a predefined shape. The sensing element may be configured to produce a signal when the sensing element interacts with the analyte. In one embodiment, the identity of the analyte may be determined by the detection of the signal and the shape of the sensing element. Using pattern recognition techniques, the analytes within a multi-analyte fluid may be characterized.
