  • Publication number: 20020051935
    Abstract: A resist composition comprising (A) a polymer comprising recurring units having an alicyclic hydrocarbon backbone to which a carboxylate moiety capable of generating carboxylic acid when decomposed under acidic conditions is attached through a C1-C20 alkylene spacer, (B) a photoacid generator, and (C) an organic solvent is sensitive to high-energy radiation, and has excellent sensitivity and resolution at a wavelength below 180 nm, and good plasma etching resistance. Because these features of the inventive resist composition enable its use particularly as a resist at the exposure wavelength of a F2 excimer laser, a finely defined pattern can easily be formed, making the resist ideal as a micropatterning material in VLSI fabrication.

  • Patent number: 6118458
    Abstract: An image displaying apparatus stores plural image data and displays one of the image data, which image data represent a growing plant (animal) or represent a series of motions of an animal. The apparatus further stores plural element data for growing the plant (animal). When one of the element data is selected, another image data of the plant (animal) is displayed in place of the previously displayed imaged data to show how the plant (animal) grew up responsive to the selected element data. The apparatus is provided with a sensor for detecting motion of a user. Detecting the motion of the user, the apparatus displays new image data representing a motion of the animal in place of the previously displayed image data to show how the animal reacts to the user's motion.

  • Patent number: 5889358
    Abstract: In a vibration gyroscope 1, a vibrator 2 is mounted to a mounting substrate 7 through support pins 6a and 6b. The mounting substrate 7 and a support substrate 10 are disposed opposite by inserting protrusions 11a and 11b of the support substrate 10 into second insertion holes 9a and 9b of the mounting substrate 7 and by supporting the mounting substrate 7 with convex molded sections 14a and 14b. The space between the substrates 7 and 10 are filled with elastic paste made up of synthetic resin such as urethan and silicone, or the like.

  • Patent number: 5880169
    Abstract: The invention provides a novel sulfonium salt having at least one acid labile group attached to a phenyl group in a molecule and a normal, branched or cyclic C.sub.1 -C.sub.20 alkylsulfonate anion. The novel sulfonium salt is effective for increasing the dissolution contrast between exposed and unexposed areas. Upon exposure, it generates an alkylsulfonic acid which is a weak acid, minimizing the influence of side reaction and deactivation during PEB step. The sulfonium salt is useful in a chemically amplified positive resist composition which lends itself to fine patterning and features high resolution.

  • Patent number: 5856561
    Abstract: Novel bisphenol carboxylic acid tertiary ester derivatives having two aromatic ether groups and an ester group which are all replaced by acid labile groups are provided. The derivatives are used as a dissolution inhibitor in a chemically amplified positive resist composition comprising an organic solvent, an alkali soluble resin, and a photo-acid generator. Since the dissolution inhibitor has a highly reactive acetal group as an acid labile group, its coupling-off rapidly takes place after exposure. The dissolution inhibitor itself is less alkali soluble and its acid decomposition product is a phenol derivative having a carboxylic acid group with high alkali solubility, leading to a high dissolution contrast.

  • Patent number: 5824824
    Abstract: The invention provides a novel sulfonium salt having at least one acid labile group attached to a phenyl group in a molecule and a C.sub.2 -C.sub.20 alkylsulfonate or arylsulfonate anion whose alkyl or aryl has as a substituent an electron withdrawing group such as fluorine and nitro group. The novel sulfonium salt is effective for increasing the dissolution contrast between exposed and unexposed areas. Upon exposure, it generates a substituted alkyl or arylsulfonic acid which is a weak acid, minimizing the influence of side reaction and deactivation during PEB step. The sulfonium salt is useful in a chemically amplified positive resist composition which lends itself to fine patterning and features high resolution.
