  • Publication number: 20240126168
    Abstract: An onium salt type monomer having the following formula (a1) or (a2).
    Type: Application
    Filed: September 12, 2023
    Publication date: April 18, 2024
    Applicant: Shin-Etsu Chemical Co., Ltd.
    Inventors: Masahiro Fukushima, Jun Hatakeyama, Masaki Ohashi
  • Patent number: 11953827
    Abstract: A molecular resist composition is provided comprising (A) a betaine type onium compound having a sulfonium cation moiety and a sulfonate anion moiety in a common molecule, the sulfonium cation moiety having a phenyl group substituted with an optionally heteroatom-containing monovalent hydrocarbon group, the phenyl group being attached to the sulfur atom, and (B) an organic solvent, the resist composition being free of a base resin. When processed by lithography using KrF, ArF excimer laser, EB or EUV, the resist composition is improved in dissolution contrast, EL, MEF, and LWR.

  • Patent number: 11940728
    Abstract: A molecular resist composition and a pattern forming process. A molecular resist composition comprising a sulfonium salt having a cation of specific structure and an organic solvent has a high sensitivity and forms a resist film with improved resolution and LWR, when processed by EB or EUV lithography. The molecular resist composition does not contain a base polymer. The molecular resist composition comprising a sulfonium salt having a cation of specific partial structure has a high sensitivity and forms a resist film with improved resolution and LWR, so that the resist composition is quite useful for precise micropatterning.

  • Patent number: 8037165
    Abstract: An information processing apparatus is provided that executes a process sequence stored in a sequence table, based on a sequence code created for each process in the process sequence. The sequence code includes a process type that specifies a sequence table, a control target that specifies a control target, and a process number that specifies one particular process in the specified process sequence.
    Type: Grant
    Filed: August 26, 2008
    Date of Patent: October 11, 2011
    Assignee: Fujitsu Limited
    Inventors: Tadashi Kameyama, Masaki Fukushima, Yoshihito Yamagami
  • Patent number: 7974203
    Abstract: The invention is directed to a traffic control system. The traffic control system comprises a communication device. The communication device includes a traffic type differentiation unit for differentiating a traffic type of an application that generates traffic to be processed on a communication network, a traffic control execution unit for controlling the traffic according to a traffic control condition corresponding to the traffic type, and a setting change reception unit for receiving setting change information on the traffic type or setting change information on the traffic control condition from the communication network. The traffic control system also comprises a setting change information transmission device provided on the communication network for transmitting setting change information.
    Type: Grant
