  • Patent number: 8318410
    Abstract: It is an object to provide a resist underlayer film forming composition having a selection ratio of dry etching rate larger than that of a resist film and exhibiting a low k value and a high n value at a short wavelength such as that of an ArF excimer laser, and enabling the formation of a resist pattern having a desired shape. When the composition is produced or used, it is required that odor due to a raw material monomer causes no problem. The object is solved by a resist underlayer film forming composition for lithography containing a polymer having in backbone thereof, a disulfide bond (S—S bond), and a solvent. The polymer may be a product of a reaction between at least one type of compound (diepoxy compound) containing two epoxy groups and at least one type of dicarboxylic acid containing a disulfide bond.

  • Patent number: 7470944
    Abstract: A solid-state image sensor of the present invention has a plurality of pixel cells that generate signal charges in accordance with incident light. It is characterized by having a gettering region within the area of a pixel cell. The gettering region, which is disposed closely to the photoelectrical conversion layer, makes direct and efficient use of gettering capability in the pixel region in the solid-state image sensor. As a result, it is possible to effectively eliminate metal contaminant contained in the pixel region, thereby remarkably reducing dark outputs occurring from the metal contaminant.
