  • Patent number: 10109529
    Abstract: A semiconductor device including a direct contact and a bit line in a cell array region and a gate electrode structure in a peripheral circuit region, and a method of manufacturing the semiconductor device are provided. The semiconductor device includes a substrate including a cell array region including a first active region and a peripheral circuit region including a second active region, a first insulating layer on the substrate, the first insulating layer including contact holes exposing the first active region, a direct contact in the contact holes, wherein a direct contact is connected to the first active region, a bit line connected to the direct contact in the cell array region and extending in a first direction, and a gate insulating layer and a gate electrode structure, wherein a dummy conductive layer including substantially the same material as the direct contact is in the peripheral circuit region.

  • Patent number: 6162460
    Abstract: Disclosed is a poultice capable of rapidly curing an affected part of a patient's body and of enhancing a curative value by increasing an infiltration efficiency of medicine into a hypodermic tissue of the affected part with the aid of a low-frequency electro therapy. Both surfaces of compress sheets of the poultice are coated with predetermined skin-adhesive medicines adapted to cure an affected part of a patient's body. A thin film is attached to lower surfaces of the compress sheets. The thin film can be detached from the lower surfaces of the compress sheets during use of the poultice. An attaching sheet for attaching the poultice to the affected part of the patient's body is located on upper surfaces of the compress sheets. A pair of conductive layers are coated on a lower surface of the attaching sheet, which is opposite to the upper surfaces of the compress sheets. A low-frequency oscillator for applying a low-frequency energy into the compress sheets is installed between the conductive layers.

  • Patent number: 5976739
    Abstract: A method of developing a screen of a cathode ray tube includes the steps of establishing an uniform electrostatic charge on selected areas of an inner surface of a panel with a predetermined pattern, rotating a nozzle to a predetermined angle with respect to the inner surface of a panel, and moving the rotated nozzle backwards and forwards while spraying a dry-powdered and electrically charged screen structure material on the selected areas of the inner surface of the panel.
