  • Method for bonding cycloolefin polymer to metal, method for producing biosensor, and biosensor
    Patent number: 11650178
    Abstract: A method for bonding a first member having a first bond-target surface made of cycloolefin polymer to a second member having a second bond-target surface made of metal. The method includes a process of exposing the first bond-target surface and the second bond-target surface to at least one of the H2O plasma and O2 plasma, as well as a process of combining the first bond-target surface and the second bond-target surface.
    Type: Grant
    Filed: December 10, 2018
    Date of Patent: May 16, 2023
    Assignee: SAMCO INC.
    Inventors: Risa Funahashi, Taichi Hashimoto, Hirokazu Terai, Fumina Miyake
  • Cycloolefin polymer bonding method
    Patent number: 11633924
    Abstract: A cycloolefin polymer (COP) bonding method wherein a first material that is COP and a second material that is COP or glass are bonded. The method includes: a step of exposing at least a bonding surface of the first material to H2O plasma; and a step of mating the bonding surface of the first material and a bonding surface of the second material. According to the method, the cycloolefin polymer (COP) can be bonded to a target material without applying high pressure or high temperature, and without affecting the optical properties.
