  • Publication number: 20070231741
    Abstract: A positive resist composition comprising a resin component having a solubility in an alkaline developer that increases under the action of an acid, a compound capable of generating an acid in response to actinic radiation, and an acidic organic compound having a molecular weight of at least 150 exhibits a high resolution and is effective in minimizing defects when processed by the photolithography. The composition is thus quite effective for precise micropatterning.

  • Patent number: 6602997
    Abstract: The present invention provides for a method for obtaining a polysaccharide substantially free from whole bacterial cells and bacterial cell debris including: (a) fermenting a Sphingomonas bacterium, which produces the polysaccharide, to produce an aqueous fermentation broth having the polysaccharide dissolved therein; (b) diluting the fermentation broth with an equal volume of deionized water; (c) partially hydrolyzing the polysaccharide by exposing the fermentation broth resulting from step (b) to a temperature in excess of 100° C.

  • Patent number: 6030817
    Abstract: A new recombinant bacteria for the production of exopolysaccharides is disclosed as well as a method for making the recombinant bacteria and making an exopolysaccharide from the bacteria by submerged aerobic fermentation of the bacteria utilizing a sugar substrate. The exopolysaccharides obtained from the inventive bacteria exhibit improved, more desirable or different properties from the exopolysaccharide produced by the non-recombinant bacteria from which the recombinant bacteria was derived. In addition, the present invention provides a method of producing bacterial exopolysaccharides by fermentation from sugar substrates that the bacteria which the exopolysaccharides are native to cannot utilize.
