    摘要： This invention relates to semiconductor devices, microelectronic devices, micro electro mechanical devices, microfluidic devices, photonic devices, and more particularly to a lithographic template, a method of forming the lithographic template and a method for forming devices with the lithographic template. The lithographic template (10) is formed having a substrate (12), a transparent conductive layer (16) formed on a surface (14) of the substrate (12) by low pressure sputtering to a thickness that allows for preferably 90% transmission of ultraviolet light therethrough, and a patterning layer (20) formed on a surface (18) of the transparent conductive layer (16). The template (10) is used in the fabrication of a semiconductor device (30) for affecting a pattern in device (30) by positioning the template (10) in close proximity to semiconductor device (30) having a radiation sensitive material formed thereon and applying a pressure to cause the radiation sensitive material to flow into the relief image present on the template. Radiation is then applied through the template so as to cure portions of the radiation sensitive material and define the pattern in the radiation sensitive material. The template (10) is then removed to complete fabrication of semiconductor device (30).

    摘要： A grayscale mask for imaging operations, including a substrate layer and a mask layer having a plurality of apertures forming a mask pattern to form a grayscale image. Each edge of each aperture includes a plurality segments forming a serrated edge, resulting in mixed edge diffraction. The apertures may be in an irregular and non-symmetric pattern and may be of variable size. A random diffusing layer may be in proximity to or integral with the substrate layer. The grayscale mask may be used for generating an optical element by printing the initial grayscale mask onto a photoresist layer and transferring the photoresist pattern onto a transparent layer and the mask may include areas or layers of variable transmission. Also described are methods for diffractive intensity averaging, diffractive error diffusion, diffractive spatial dithering, and diffractive intensity averaging.

    摘要： A polymerizable composition comprising an effective amount of at least one tetrafunctional acrylate monomer. In one embodiment of the invention, a polymerizable composition is a compound comprising of at least 50 percent by weight of at least one tetrafunctional acrylate monomer, from 5 to 20 percent by weight of at least one modified bisphenol A epoxy diacrylate monomer, from 0 to 25 percent by weight of at least one acrylate monomer selected from aliphatic difunctional and polyfunctional acrylates, from 0 to 3 percent by weight of at least one UV absorber, and a source of free radicals. The lens-forming material resulted from the polymerizable composition is introduced to a lens mold with a mold cavity having a configuration conforming to the optical lens to be molded. A radiation energy source is used to cure the lens-forming material in the filled mold. The radiation energy source comprises a U-shaped UV light. The U-shaped UV light has a first arm capable of delivering UV light in a first direction and a second arm capable of delivering UV light in an opposite second direction. The first and second arms are spaced apart and substantially parallel to each other, thereby defining a space therebetween. The filled mold is placed at the center of the space therebetween the first and second arms to receive the radiations from the first and second directions for curing. The resultant lens has an inherently integrated nullhard-soft-hardnull structure cross-sectionally.

    摘要： The invention relates to ophthalmic molding formulations and to tinted, high Dk ophthalmic moldings. This invention also relates to a method for making a tinted ophthalmic molding. The method comprises: (a) providing a polymer precursor having cross-linkable or polymerizable groups; (b) providing a pigment dispersion comprising an inorganic or organic pigment and a dispersing agent; (c) mixing the pigment dispersion with the polymer precursor to form a tinted prepolymer mixture; (d) dispensing the tinted prepolymer mixture into a mold; and (e) forming a tinted ophthalmic molding from the tinted prepolymer mixture, the molding comprising a polymer matrix having the pigment entrapped therein. With this method, tinted ophthalmic moldings, particularly edge-to-edge soft, tinted contact lenses having improved properties, are prepared with an improved efficiency.

    摘要： It is an object to establish a sterilization condition and means for decreasing the amount of a remaining sterilization agent as much as possible after sterilizing a rubbery sealing tool. In a sterilizing method using gaseous hydrogen peroxide, a filling rate of a sample in a sterilization bag for a normal type is set to 45% or more and a sterilization condition is set to a hydrogen peroxide treatment of 3 pulses and an aeration pulse of 20 pulses, thereby carrying out a sterilization treatment. Furthermore, it is preferable that a volume rate in a bag of an outer bag accommodating the sterilization bag should be set to 55 to 12%. By such setting, a survival ratio of 0/10 of a bacteria cell could be realized at first to fifth times of repetition of the sterilization treatment.

    摘要： A method of cast molding an intraocular implant from two or more dissimilar materials using disposable molds. The subject cast molding method is particularly useful in the production of intraocular lenses manufactured from dissimilar materials. It is desirable to produce intraocular lenses from dissimilar materials in order to optimize the optical characteristics of the intraocular lens optic portion and to optimize stability and flexibility characteristics of the intraocular lens haptic elements.
