  • Patent number: 8946631
    Abstract: A substrate is irradiated by primary electrons and secondary electrons generated from the substrate are detected by a detector. A reference die is placed on the stage to obtain a pattern matching template image including feature coordinates of the reference die. A pattern matching is performed with an arbitrary die in a row or column including the reference die using the template image to obtain feature coordinates of the arbitrary die. An angle of misalignment is calculated between the direction of the row or column including the reference die and one of the directions of movement of the substrate on the basis of the feature coordinates of the arbitrary die and those of the reference die. The stage is rotated to correct the angle of misalignment to conform the direction of the row or column including the reference die with the one of the directions of movement of the substrate.

  • Patent number: 7264918
    Abstract: A resist composition for liquid immersion lithography process, which comprises: (A) a polymer comprising (a1) alkali-soluble constitutional units each comprising an alicyclic group having both (i) a fluorine atom or a fluoroalkyl group and (ii) an alcoholic hydroxyl group, wherein the polymer changes in alkali-solubility due to the action of acid; and (B) an acid generator which generates acid due to exposure to light, and a method for forming a resist pattern using the resist composition. By the resist composition or the method, an adverse effect of the immersion liquid can be avoided while achieving high resolution and high depth of focus.

  • Patent number: 7244546
    Abstract: A planographic printing plate precursor includes a substrate and an image recording layer provided thereon, the image recording layer being capable of recording through exposure to an infrared ray and containing at least (A) an infrared absorbing agent, (B) a polymerization initiator comprising an onium salt formed by an onium cation and a carboxylic acid anion, where the carboxylic acid anion has an acid group, a hetero atom and an aromatic group, (C) a polymerizable compound and (D) a binder polymer. The planographic printing plate precursor is exposed imagewise with an infrared laser. Then, printing is carried out using the exposed planographic printing plate precursor, which is set in a printer without being subjected to any developing process, by feeding an oil based ink and an aqueous component onto the planographic printing plate precursor. Unexposed areas of the planographic printing plate precursor are removed during the printing process.

  • Patent number: 7232649
    Abstract: An improved method of manufacturing a photosensitive printing element that minimizes relief variation and improves image fidelity. The method involves a step of pre-curing the first (floor layer) of photocurable material prior to depositing an additional layer or layers of photocurable material that may be imaged and developed to produce a desired relief image on the surface of the photosensitive printing element. The photosensitive printing element is then thermally developed by contacting the photosensitive printing element with at least one roll that is capable of moving over at least a portion of the imaged surface of the flexographic printing element to remove the softened or melted non-crosslinked photopolymer.
