  • Patent number: 7862982
    Abstract: A new lithographic process comprises reducing the linewidth of an image while maintaining the lithographic process window, and using this process to fabricate pitch split structures comprising nm order (e.g., about 22 nm) node semiconductor devices. The process comprises applying a lithographic resist layer on a surface of a substrate and patterning and developing the lithographic resist layer to form a nm order node image having an initial line width. Overcoating the nm order node image with an acidic polymer produces an acidic polymer coated image. Heating the acidic polymer coated image gives a heat treated coating on the image, the heating being conducted at a temperature and for a time sufficient to reduce the initial linewidth to a subsequent narrowed linewidth. Developing the heated treated coating removes it from the image resulting in a free-standing trimmed lithographic feature on the substrate. Optionally repeating the foregoing steps further reduces the linewidth of the narrowed line.

  • Patent number: 7846639
    Abstract: The invention relates to an imaging element and a method of using the imaging element to form a recording element. The imaging element includes a composition sensitive to actinic radiation from a source of radiation having a range of wavelengths and a photoluminescent tag that is responsive to at least one wavelength from the source of radiation. The photoluminescent tag can be used to authenticate the identity of the element, provide information about the element, and/or to establish one or more conditions in a device used to prepare the recording element from the imaging element.

  • Patent number: 7838200
    Abstract: A method and a resist composition. The resist composition includes a polymer having repeating units having a lactone moiety, a thermal base generator capable of generating a base and a photosensitive acid generator. The polymer has the properties of being substantially soluble in a first solvent and becoming substantially insoluble after heating the polymer. The method includes forming a film of a photoresist including a polymer, a thermal base generator capable of releasing a base, a photosensitive acid generator, and a solvent. The film is patternwise imaged. The imaging includes exposing the film to radiation, resulting in producing an acid catalyst. The film is developed in an aqueous base, resulting in removing base-soluble regions and forming a patterned layer. The patterned layer is baked above the temperature, resulting in the thermal base generator releasing a base within the patterned layer and the patterned layer becoming insoluble in the solvent.

  • Patent number: 7833692
    Abstract: Novel, poison-blocking compositions and methods of using those compositions to form poison-blocking layers are provided. The compositions comprise a typical composition used in microlithographic processes, but with a poison-blocking additive included in that composition. The preferred additive is a compound comprising one or more blocked isocyanates. Upon heating to certain temperatures, the blocking group is released from the isocyanate, leaving behind a moiety that is highly reactive with the poisonous amines generated by typical dielectric layers.
