  • 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.

  • Publication number: 20180301368
    Abstract: A wafer processing device is a device for handling a framed wafer including a frame, a film stretched inside the frame, and a wafer attached on the film, to perform a plasma processing on the wafer. The device includes: a wafer stage on which the wafer is to be placed via the film; a plurality of vertically movable frame-lifting pins arranged around the wafer stage, for supporting the frame; and a frame-lifting-pin drive controller for lowering the individual frame-lifting pins with different timings. With this device, the film with the attached wafer can be neatly placed on the wafer stage (i.e. with no wrinkle in the film as well as no bubble between the film and the wafer stage).

  • Patent number: 9488519
    Abstract: The present invention provides a light beam measuring instrument that can securely receive light reflected by a sample. The light beam measuring instrument 1 includes an optical axis tilting mechanism 13 that includes a first tilting mechanism 131 and a second tilting mechanism 132. From the optical axis A1 of irradiation light beam emitted from a light beam source 112, the first tilting mechanism 131 tilts the optical axis A1 about the first tilting axis T1. The second tilting mechanism 132 tilts the optical axis A1 about the second tilting axis T2. The light beam measuring instrument 1 can receive the light reflected by the semiconductor chip C by means of operation of the optical axis tilting mechanism 13 even if the light reflected by the semiconductor chip C is tilted. Accordingly, this apparatus can securely perform measurement or inspection using the light beam.

  • Patent number: 8314560
    Abstract: An induction coil composed of n pieces of identically shaped coil elements (where n is equal to or greater than two), which are rotation-symmetrically arranged with respect to an axis normal to the surface of an object to be processed, is provided above the object, the coil elements being electrically connected in parallel. Each of the coil elements of the induction coil encircles the aforementioned axis, with the ground end and the feed end located at the same position on a projection plane on the object with the ground end under the feed end. Each coil element has a bottom portion shaped like an arc having a predetermined width and a central angle of 360°/n, with the ground end at one end thereof, and a feed portion shaped like an arc having a predetermined width, with the feed end at one end thereof, the feed portion being located above the bottom portion and electrically connected to the same bottom portion.
