  • Patent number: 6864045
    Abstract: A radiographic silver halide film comprises a cubic grain silver halide emulsion layer on one side of the support and a tabular grain silver halide emulsion layer on the other side. The cubic grain silver halide emulsion layer comprises a combination of first and second spectral sensitizing dyes that provides a combined maximum J-aggregate absorption on the cubic silver halide grains of from about 540 to about 560 nm. The first spectral sensitizing dye is an anionic benzimidazole-benzoxazole carbocyanine, the second spectral sensitizing dye is an anionic oxycarbocyanine. The cubic grain silver halide emulsion layer also includes a mixture of gelatin or a gelatin derivative and a second hydrophilic binder other than gelatin or a gelatin derivative at a weight ratio of first to second hydrophilic binder of from about 2:1 to about 5:1. The cubic silver halide grains comprise from about 1 to about 20 mol % chloride and from about 0.25 to about 1.

  • Patent number: 6861204
    Abstract: A method for defining a full phase layout for defining a layer of material in an integrated circuit is described. The method can be used to define, arrange, and refine phase shifters to substantially define the layer using phase shifting. Through the process, computer readable definitions of an alternating aperture, dark field phase shift mask and of a complimentary mask are generated. Masks can be made from the definitions and then used to fabricate a layer of material in an integrated circuit. The separations between phase shifters, or cuts, are designed for easy mask manufacturability while also maximizing the amount of each feature defined by the phase shifting mask. Cost functions are used to describe the relative quality of phase assignments and to select higher quality phase assignments and reduce phase conflicts.

  • Patent number: 6861183
    Abstract: A mask used for imaging nearly dense features in a substrate. Scatter dots are disposed on the mask in proximity to the nearly dense features, where the scatter dots adjust photon levels of the nearly dense features to a desired level. The adjustment is controlled by selective adjustment of a duty cycle and degree of stagger of the scatter dots. In this manner, the scatter dots adjust the optical properties of the nearly dense features to be very similar to the optical properties of dense features, which enables more accurate imaging of the nearly dense features on the substrate. However, because the scatter dots are discontinuous, they do not overcorrect in the same manner that a scatter bar formed at a minimum resolution might overcorrect. Further, there is a reduced likelihood that the scatter dots would actually print on the substrate.

  • Patent number: 6852454
    Abstract: This invention relates to semiconductor devices, microelectronic devices, microelectromechanical devices, microfluidic devices, photonic devices, and more particularly to a multi-tiered lithographic template, a method of forming the multi-tiered lithographic template and a method for forming devices with the multi-tiered lithographic template. The multi-tiered lithographic template (10/10?) is formed having a first relief structure and a second relief structure, thereby defining a multi-tiered relief image. The template is used in the fabrication of a semiconductor device (40) for affecting a pattern in device (40) by positioning the template in close proximity to semiconductor device (40) having a radiation sensitive material formed thereon and applying a pressure to cause the radiation sensitive material to flow into the multi-tiered relief image present on the template.

  • Patent number: 6841314
    Abstract: Photomask blanks are fabricated by forming half-tone film over quartz substrate and causing a half-tone phase shift film to contain impurity becoming a color center by implanting ion at a predetermined depth of the half-tone film by means of ion-implantation. Using the above photomask blanks, a desired pattern is formed within photosensitive resist by applying photosensitive resist over the half-tone film thereover, exposing the resist through use of a desired pattern, and then developing the resist. Through the above photosensitive resist as a mask, the half-tone film is etched to form a predetermined pattern within the half-tone film. The exposed photosensitive resist is removed to fabricate a photomask.

  • Patent number: 6838232
    Abstract: At least one of a nucleus forming process, a nucleus growing process, a chemical sensitizing process, and a spectral sensitizing process for producing a silver halide photographic emulsion is performed by using a microreactor. A minute region of the microreactor is used to precisely perform a reaction of nucleus formation. A condition under which host grains are allowed to react with newly supplied silver halide nuclei is made uniform to cause uniform crystal growth. A predetermined quantity of molecules for chemical sensitization is doped in a crystal lattice of a nucleus of silver halide to effect a sensitizing process. Alternatively, a spectral sensitizing process in which a single molecular layer of a spectral sensitizer is uniformly adsorbed on a silver halide nucleus grain surface is securely carried out.
