  • Patent number: 6809334
    Abstract: The invention relates to a semiconductor integrated circuit and a method of manufacturing the same, and particularly, to prevention of a drop in the performance and reliability of a semiconductor integrated circuit device, which would otherwise be induced by degassing arising in a TEOS/CVD silicon oxide film provided on a back surface of a semiconductor substrate. There are proposed a semiconductor substrate in which a TEOS/CVD silicon oxide film provided on a back surface of the semiconductor substrate is coated with another dielectric film; a semiconductor substrate not having a TEOS/CVD silicon oxide film on a back surface thereof; a semiconductor substrate in which a TEOS/CVD silicon oxide film is removed from a back surface of the substrate; and a semiconductor substrate in which a thin TEOS/CVD silicon oxide film—which involves degassing falling within a tolerance is provided on a back surface of the substrate.

  • Publication number: 20040088327
    Abstract: A sentence generating method and apparatus for generating a joke sentence set having a dual meaning. A predetermined word in a selected first idiom is stored in a W list. A word of analogous sound having the pronunciation same as or analogous with the word in the W list and also being of the same word class as the word in the W list is stored in a RW list. It is then checked whether or not the subject word stored in the P list has a semantic relationship with the word of the analogous sound in the RW list. If the result of check is affirmative, a first joke sentence having the subject word in the P list and composed of the subject word of the P list and the first idiom is generated. A second idiom, corresponding to the first idiom, in which the word in the W list is replaced by the word of the analogous sound in the RW list, is generated, and a second joke sentence composed of the subject word of the P list and the second idiom is generated.

  • Publication number: 20030052979
    Abstract: In an image conversion method and apparatus, luminance Y3 of each pixel of a converted image is obtained by use of an expression Y3=C1Y1+C2Y2 and from luminance Y1 of a corresponding pixel of a source image, luminance Y2 of a corresponding pixel of a low frequency image, and C1 and C2 which are functions of the luminance Y2. Since C1+C2 is constant when Y2≦T2, contrast of a low frequency component can be prevented from decreasing. In a portion in which the luminance Y2 of the low frequency image is low, the low frequency image is enhanced. In a portion in which the luminance Y2 of the low frequency image is high, the low frequency image is suppressed. In a method and apparatus for detecting noise level of an original signal in real time, a plurality of local regions are set on an input image in such a manner that the local regions are distributed uniformly over the entire area of an image. In each local region, determination as to whether or not luminance is saturated is performed.

  • Patent number: 6313032
    Abstract: A method for manufacturing a salicide transistor, a semiconductor storage, and a semiconductor device that can solve both an increase in narrow-line resistance and an increase in P-N-junction leakage, and can give an optimized process as the total LSI device manufacturing process flow. After adding an impurity in the high-concentration source/drain region on a semiconductor substrate, a heat treatment is performed at a first temperature, then a heat treatment is performed for forming salicide at a second temperature higher than a predetermined temperature and lower than the first temperature for a first period of time, an interlayer insulating film is formed, and heat treatment is performed at a third temperature higher than the second temperature and lower than the first temperature. Since the crystallinity of the implanted layer 109 has been recovered before forming the silicide protecting film, salicide can be formed under the conditions where the crystallinity of the diffusion layer is good.

  • Publication number: 20010021830
    Abstract: A compact liquid discharge regulator is provided at low cost by arranging a channel spirally formed in the surface of a passage forming member. The surface of the passage forming member is brought into close contact with the inner surface of a housing part, and the channel functions as a liquid passage. In this construction, the sectional form and length of the channel can be formed at high precision in accordance with the design. Therefore, a desired pipe loss is obtainable only by designing in advance the sectional form and length of the channel so as to correspond to the pipe loss. Particularly, with injection molding, mass production of a passage forming member of identical pipe loss can be effected merely by preparing a mold corresponding to the pipe loss, thus leading to a considerable reduction in the manufacturing cost of the discharge regulator.
