  • Publication number: 20110287595
    Abstract: Interconnections are formed over an interlayer insulating film which covers MISFETQ1 formed on the principal surface of a semiconductor substrate, while dummy interconnections are disposed in a region spaced from such interconnections. Dummy interconnections are disposed also in a scribing area. Dummy interconnections are not formed at the peripheries of a bonding pad and a marker. In addition, a gate electrode of a MISFET and a dummy gate interconnection formed of the same layer are disposed. Furthermore, dummy regions are disposed in a shallow trench element-isolation region. After such dummy members are disposed, an insulating film is planarized by the CMP method.

  • Publication number: 20110281491
    Abstract: A method of manufacturing a display device includes the steps of: forming a positive type photoresist above a surface of a first transparent substrate having a transistor formed on the surface thereof so as to cover the transistor; radiating a light from a back surface side of the first transparent substrate to the first transparent substrate having the positive type photoresist formed thereabove, for exposing the positive type photoresist; developing the positive type photoresist thus exposed to selectively leave the positive type photoresist located above the transistor, for forming a spacer; and laminating a second transparent substrate above the surface of the first transparent substrate through the spacer.

  • Patent number: 7838402
    Abstract: A method of manufacturing an electronic apparatus having a resist pattern provided over a substrate provided with a thin film transistor, the method includes the steps of forming by application a resist film over the substrate in the state of covering the thin film transistor, forming a resist pattern by subjecting the resist film to exposure to light and a developing treatment, and irradiating the resist pattern with at least one of ultraviolet light and visible light in a dry atmosphere in the condition where a channel part of the thin film transistor is prevented from being irradiated with light having a wavelength of shorter than 260 nm, wherein a step of heat curing the resist pattern is conducted after the irradiation with at least one of ultraviolet light and visible light.
