  • Publication number: 20160275371
    Abstract: Disclosed is a jig for matching images between a color camera and an infrared camera so as to match images into one image by correcting angles of view and degrees of distortion according to physical positional relations between the images. The jig includes a white background board having square or circular holes arranged by designated intervals in the horizontal and vertical directions and a black inner board detachably combined with the white background board so that holes formed on the white background board are expressed as black. The white background board and the black inner board are respectively kept in a normal temperature state and a refrigerated state and then combined so that, if the infrared camera is used to photograph, a black square or circular pattern may be extracted according to a temperature difference between the two boards.

  • Patent number: 7871885
    Abstract: Embodiments relate to a manufacturing method of a flash memory device which improves electrical characteristics by reducing or preventing void generation. A manufacturing method of a flash memory device according to embodiments includes forming a plurality of gate patterns over a semiconductor substrate including a tunnel oxide layer, a floating gate, a dielectric layer, and a control gate. A spacer layer may be formed as a compound insulating layer structure over the side wall of the gate pattern. A source/drain area may be formed over the semiconductor substrate at both sides of the control gate. An insulating layer located at the outermost of the spacer layer may be removed. A contact hole may be formed between the gate patterns by forming and patterning the interlayer insulating layer. A contact plug may be formed in the contact hole.

  • Patent number: 7858473
    Abstract: A flash memory device having a spacer of a gate region formed in an oxide-nitride-oxide (ONO) structure and a source/drain region formed using the ONO structure. The outermost oxide in the ONO structure is removed and an interlayer insulating film is formed to ensure sufficient space between the gate regions. Thus, it is possible to prevent a void from being generated in the interlayer insulating film and prevent a word line from being electrically connected to a drain contact for forming a bit line.
