  • Patent number: 8221961
    Abstract: The present invention relates to a method of manufacturing semiconductor devices. According to the method, an etch target layer, a chemically amplified photoresist layer, and an Anti-Reflective Coating (ARC) layer are first sequentially formed over a semiconductor substrate. An exposure process is performed in order to form exposure portions in the photoresist layer. A thermal process is performed so that a decrosslinking reaction is generated in the ARC layer on the exposure portions. A development process is performed in order to form photoresist layer patterns and ARC layer patterns by removing the ARC layer at portions in which the decrosslinking reaction has occurred and the exposure portions. A silylation process is performed in order to form silylation patterns on sidewalls of each of the photoresist layer patterns. The ARC layer patterns and the photoresist layer patterns are removed. The etch target layer is patterned using the silylation patterns as an etch mask.

  • Patent number: 8085434
    Abstract: The appearance of a color print viewed under UV illumination is predicted using a target comprising color patches each printed using a known coverage of printer colorant(s). In one case, the target is illuminated using a UV light source and an electronic image of the target is captured using a digital camera or the like. In another case, a spectrophotometer is used both with and without a UV cutoff filter to measure the target. The captured image data or the spectrophotometric measurements are used to derive a UV printer characterization model that relates any arbitrary combination of printer colorants to a predicted UV color appearance value. Metameric colorant mixture pairs for visible light and UV light viewing can be determined using the UV model together with a conventional visible light printer characterization model. A visual matching task is used to determine a correction factor for the UV printer characterization model.

    Abstract: The invention relates to a method for producing a substrate having a resist layer in the form of a relief structure, which represents a diffraction structure. The resist layer at least in certain areas adjoins a conductive layer, which scatters the primary electrons and/or produces secondary electrons when the resist layer is exposed by means of an electron beam. With this method the material of the resist layer and the conductive layer and the exposure parameters are adjusted to each other such that the resist layer is also exposed outside the area impinged with the electron beam such that the flanks of the relief structure obtain an inclined form.

  • Patent number: 7361455
    Abstract: Anti-reflective materials such as bottom anti-reflective coatings (BARC's) and sacrificial light absorbing materials (SLAM) may be made more effective at preventing coherent light or electron beam reflection from a substrate by including in the anti-reflective material an additive to alter the radiation beam path of the reflected light or electrons. The radiation beam path altering additive may be a reflective material or a refractive material. The inclusion of such a radiation beam bath altering additive may reduce line width roughness and increase critical dimension (CD) control of interconnect lines and vias.

  • Publication number: 20040096768
    Abstract: A radiographic silver halide film useful for mammography comprises a support having a cubic grain silver halide emulsion on one side. The cubic grains are spectrally sensitized with a combination of first and second spectral sensitizing dyes that provides a combined maximum J-aggregate absorption of from about 540 to about 560 nm. The first spectral sensitizing dye is an anionic benzimidazole-benzoxazole carbocyanine and the second spectral sensitizing dye is an anionic oxycarbocyanine. The first and second spectral sensitizing dyes are present in a molar ratio of from about 0.25:1 to about 4:1.

  • Patent number: 6730454
    Abstract: Antireflective compositions characterized by the presence of an SiO-containing polymer having chromophore moieties and transparent moieties are useful antireflective hardmask compositions in lithographic processes. These compositions provide outstanding optical, mechanical and etch selectivity properties while being applicable using spin-on application techniques. The compositions of the invention are advantageously useful with shorter wavelength lithographic processes and/or have minimal residual acid content.
