  • Patent number: 8415186
    Abstract: The present invention provides a method of super flat chemical mechanical polishing (SF-CMP) technology, which is a method characterized in replacing laser lift-off in a semiconductor fabricating process. SF-CMP has a main step of planting a plurality of polishing stop points before polishing the surface, which is characterized by hardness of the polishing stop points material being larger than hardness of the surface material. Therefore, the present method can achieve super flat polishing surface without removing polishing stop points.

  • Patent number: 8217396
    Abstract: The present invention provides a method for manufacturing a highly reliable display device at a low cost with high yield. According to the present invention, a step due to an opening in a contact is covered with an insulating layer to reduce the step, and is processed into a gentle shape. A wiring or the like is formed to be in contact with the insulating layer and thus the coverage of the wiring or the like is enhanced. In addition, deterioration of a light-emitting element due to contaminants such as water can be prevented by sealing a layer including an organic material that has water permeability in a display device with a sealing material. Since the sealing material is formed in a portion of a driver circuit region in the display device, the frame margin of the display device can be narrowed.

  • Patent number: 8120077
    Abstract: Capacitance between a detection capacitor and a reset transistor is the largest among the capacitances between the detection capacitor and transistors placed around the detection capacitor. In order to reduce this capacitance, it is effective to reduce the channel width of the reset transistor. It is possible to reduce the effective channel width by distributing, in the vicinity of the channel of the reset transistor and the boundary line between an active region and an element isolation region, ions which enhance the generation of carriers of an opposite polarity to the channel.
