  • Publication number: 20150337494
    Abstract: A roll apparatus includes a suction roll, a suction mechanism, and a gas-permeable member. The suction roll is rotatable and has an outer circumferential surface and an inside defined by the outer circumferential surface. The suction mechanism generates a suction force toward the inside from an outside of the suction roll. The gas-permeable member covers the outer circumferential surface of the suction roll. The gas-permeable member and the suction roll allow water vapor to be uniformly extracted from an object to be processed while the object to be processed is pressed by means of the gas-permeable member. The roll apparatus of the present invention is capable of producing a member having a concave-convex structure to be used for diffracting or scattering light at a high yield and high throughput.

  • Patent number: 7019393
    Abstract: On a glass substrate of a liquid crystal display device, electrode parts to which metallic electrodes (bumps) of an IC circuit are connected from an upper part are formed. The electrode parts are formed by opening an interlayer dielectric film at parts corresponding to metal wiring and forming land shaped electrode pads in the opening parts. In this invention, the planar forms of the electrode pads are smaller than the opening parts of the interlayer dielectric film. Thus, the planarization of the peripheral surfaces around the electrode parts is improved. Accordingly, integrated circuit devices (IC) or semiconductor chips can be connected with high reliability.
