  • Publication number: 20230387682
    Abstract: A control method for causing a computer to execute processing of: acquiring supply information indicating supply power supplied to a power grid and grid information indicating a grid capacity of the power grid; determining whether or not the supply power exceeds the grid capacity based on the supply information and the grid information; and if it is determined that the grid capacity is exceeded, performing control so that surplus power exceeding the grid capacity is supplied to a computing device constituting a predetermined distributed computing system.

  • Patent number: 11217604
    Abstract: An active region includes a body region in which first and second transistors are formed, a connection portion to which a potential of the body region is connected, and a lead portion that connects the body region and the connection portion. Source regions or drain regions of the first and second transistors formed in the body region are provided in a common region. Each of the lead portions extends from a corresponding channel region such that the lead portions are isolated from each other, and a gate electrode extends thereon. A width of the lead portion is narrower than a distance between corresponding ones of contact portions of the source regions and the drain regions of the first and second transistors. A width of the connection portion is equal to or narrower than a gate width of the gate electrode extending on the lead portion.

  • Patent number: 7638395
    Abstract: A method for fabricating a semiconductor device is provided which has first and second regions, transistors of different conductivity types being formed on parts of a substrate corresponding to the first and second regions. The method includeujs the steps of: (a) forming a first insulating film to cover the parts of the substrate corresponding to the first and second regions; (b) forming a first thin film on the first insulating film, the first thin film having a relatively higher etching rate than the first insulating film in plasma etching using a halogen gas; and (c) removing a part of the first thin film corresponding to the first region by the plasma etching using a mask covering the second region and modifying a part of the first insulating film corresponding to the first region.

  • Patent number: 6794677
    Abstract: Variations in the size of a linear pattern resulting from difference in mask pattern layout are prevented by setting the perimeter of the linear pattern per unit area in a specified range irrespective of the type of a semiconductor integrated circuit device or by adjusting a process condition in accordance with type-to-type difference in the perimeter of the linear pattern per unit area.

  • Patent number: 6187688
    Abstract: After an organic bottom anti-reflective coating (12) is deposited on an underlying film (11), a resist pattern (15) is formed on the organic bottom anti-reflective coating (12). Dry etching is performed with respect to the organic bottom anti-reflective coating (12) masked with the resist pattern (15) to form an anti-reflective coating pattern. The dry-etching of the organic bottom anti-reflective coating (12) is performed by using etching gas containing gas having the S component such as SO2/O2-based etching gas or COS/O2-based etching gas.

  • Patent number: 5108953
    Abstract: A method for fabricating a semiconductive device is described, wherein a semiconductive substrate having a thermally shrinkable, refractory metal silicide thin film is provided, on which an insulating film on the metal silicide thin film is formed. The metal silicide thin film is thermally treated in an atmosphere containing hydrogen. By this, no morphological degradation is observed in the silicide thin film without an increase of the resistance.
