  • Solutions and processes for removal of sidewall residue after dry etching
    Publication number: 20040016719
    Abstract: The present invention relates to a novel process for removing sidewall residue after dry-etching process. Conventionally, after dry-etching, photoresist and sidewall residues are removed by ozone ashing and hot sulfuric acid. Normally, they are hard to be removed completely. It was found in the present invention that the addition of fluorine-containing compound, preferably hydrogen fluoride and ammonium fluoride, in sulfuric acid results in complete removal of photoresist and sidewall residue without the need for stripper. The process is simple and does not affect the original procedures or the other films on the substrate. The present invention also relates to a novel solution for removing sidewall residue after dry-etching, which comprises sulfuric acid and a fluorine-containing compound, preferably hydrogen fluoride and ammonium fluoride, in the range of from 10:1 to 1000:1 by weight.

  • Mouse growth hormone secretagogue receptor
    Patent number: 6682908
    Abstract: A mouse growth hormone secretagogue receptor has been isolated, cloned and sequenced. This receptor is characteristic of the G-protein family of receptors. Mouse growth hormone secretagogue receptors may be used to screen and identify compoumds which bind to the mouse growth hormone secretagogue receptor. Such compounds may be used in the treatment of conditions which occur when there is a shortage of growth hormone, such as observed in growth hormone deficient children, elderly patients with musculoskeletal impairment and those recovering from hip fracture and osteoporosis. Targeted disruption of the mouse GHS-R gene may prove useful in elucidation of the mechanism of action and role of the growth hormone secretagogues in human and animal physiology.
