  • Patent number: 7253112
    Abstract: A method of fabricating semiconductor devices using dual damascene processes to form plugs in the via holes composed of various high etch materials and bottom anti-reflection coating (BARC) materials. After via hole etch, a layer of high etch rate plug material is spin coated to fill the via holes. Next, a layer of photoresist is applied. The photoresist is then exposed through a mask and developed to form an etch opening. Using the remaining photoresist as an etch mask and with a bottom anti-reflection coating (BARC) as protection, the oxide or low k layer is etched to form subsequent wiring. The etch step is known as a damascene etch step. The remaining photoresist is removed and the trench/via openings are filled with metal forming inlaid metal interconnect wiring and contact vias.

  • Patent number: 7253118
    Abstract: Differently-sized features of an integrated circuit are formed by etching a substrate using a mask which is formed by combining two separately formed patterns. Pitch multiplication is used to form the relatively small features of the first pattern and conventional photolithography used to form the relatively large features of the second pattern. Pitch multiplication is accomplished by patterning a photoresist and then etching that pattern into an amorphous carbon layer. Sidewall spacers are then formed on the sidewalls of the amorphous carbon. The amorphous carbon is removed, leaving behind the sidewall spacers, which define the first mask pattern. A bottom anti-reflective coating (BARC) is then deposited around the spacers to form a planar surface and a photoresist layer is formed over the BARC. The photoresist is next patterned by conventional photolithography to form the second pattern, which is then is transferred to the BARC.

The catalyst is formed from a chemical composition including a hexaaluminate, a metal hydroxide and a precious metal. The composition may be disposed on a support or may be extruded or cast into or onto a support. Incorporation of hexaaluminates allows inclusion of metal hydroxides that flux the active precious metal surface at higher temperatures than can aluminum oxide-based catalytic compositions, thereby enhancing resistance of the catalyst and monolithic support and increasing the durability and thermal range of the PROX catalyst. An additional advantage is that lesser amounts of precious metal oxides need be deposited onto the hexaaluminate, while retaining activity similar to aluminum oxide compositions.

  • Patent number: 7253151
    Abstract: The present invention relates to the IL-12p40 subunit mutant gene which can produce IL-12(interleukin 12) of human and mouse origin with high activity, the expression vector including above mutant gene and the use of them to DNA vaccine adjuvant. Particularly, it relates to IL-12p40 mutant gene which inhibits the secretion of IL-12p40 but normally secretes active IL-12p70 by making mutation at Asn-222(human) or Asn-220(mouse) amino acid of IL-12p40, which acts as a competitive inhibitor of active form of IL-12, IL-12p70. Therefore, the IL-12p40 mutant gene of the present invention can be useful for DNA vaccination and gene therapy against various diseases, for example, AIDS, hepatitis C or hepatitis B, cancer, influenza, tuberculosis and malaria, which essentially require cellular immune responses for their therapy.
