  • Patent number: 10544041
    Abstract: To form graphene to a practically even thickness on an object having an uneven surface or a complex surface, in particular, an object having a surface with a three-dimensional structure due to complex unevenness, or an object having a curved surface. The object and an electrode are immersed in a graphene oxide solution, and voltage is applied between the object and the electrode. At this time, the object serves as an anode. Graphene oxide is attracted to the anode because of being negatively charged, and deposited on the surface of the object to have a practically even thickness. A portion where graphene oxide is deposited is unlikely coated with another graphene oxide. Thus, deposited graphene oxide is reduced to graphene, whereby graphene can be formed to have a practically even thickness on an object having surface with complex unevenness.

  • Patent number: 10050132
    Abstract: A change in electrical characteristics is suppressed and reliability in a semiconductor device using a transistor including an oxide semiconductor is improved. One feature resides in forming an oxide semiconductor film over an oxygen-introduced insulating film, and then forming the source and drain electrodes with an antioxidant film thereunder. Here, in the antioxidant film, the width of a region overlapping with the source and drain electrodes is longer than the width of a region not overlapping with them. The transistor formed as such has less defects in the channel region, which will improve reliability of the semiconductor device.
