  • Patent number: 6774020
    Abstract: Insulating films 34 through 38 (of which insulating films 34, 36, 38 are silicon nitride films and insulating films 35, 38 are silicon oxide films) are sequentially formed on the wires 33 of the fourth wiring layer and groove pattern 40 is transferred into the insulating film 38 by means of photolithography. An anti-reflection film 41 is formed to fill the grooves 40 of the insulating film 38 and then a resist film 42 carrying a hole pattern 43 is formed. The films are subjected to an etching operation in the presence of the resist film 42 to transfer the hole pattern into the insulating films 38, 37, 36 and part of the insulating film 35. Subsequently, the resist film 42 and the anti-reflection film 41 are removed and the groove pattern 40 and the hole pattern 43 are transferred respectively into the insulating film 37 and the insulating film 35 by using the insulating film 38 as mask.

  • Patent number: 6698298
    Abstract: A torque wrench for additional tightening inspection can measure a precise torque value by simply tightening the tightening bolt additionally. When the inspection bolt is tightened, the rotation of the wrench is detected before the rotation of the bolt due to the torsion of the wrench itself. The intersection P between a torque gradient line M obtained at that time and a torque gradient line N of a rotating state after the rotation of the bolt makes a measuring point. The torque value at this intersection P is determined to obtain a torque measurement. Here, the torque gradient line N is obtained by connecting several points each corresponding to a torque value of 90% of the torque value TA at the intersection PA with a referential torsional torque gradient line L.

  • Patent number: 6686619
    Abstract: A semiconductor integrated circuit device and a manufacturing method therefor provide advantages that undulations are prevented from being produced in polycrystal silicon plugs in bit line contact holes and that the undesired phenomenon of transversally etching silicide film at contacts of the bit lines and the polycrystal silicon plugs is avoided. The bit lines formed when forming a first wiring layer are made of a laminate film having a titanium film, a titanium nitride film and a tungsten film, and a titanium silicide film containing nitrogen or oxygen is formed in contact areas of the bit lines and plugs. A titanium silicide film containing nitrogen or oxygen is also formed in contact areas of the first wiring layer and semiconductor substrate. The titanium silicide film may be replaced by silicide film containing nitrogen or oxygen, cobalt silicide film containing nitrogen or oxygen or cobalt silicide film.

  • Publication number: 20030112725
    Abstract: In step S1, the address generator generates address information composed of a sync signal which is recorded on an optical disc, address data and an error correction code for the address data, pre-encodes and supplies it to a modulator. At the same time, a carrier signal generator generates a carrier signal which is to carry the address information, and supplies it to the modulator. In step S2, the modulator makes MSK modulation of the carrier signal supplied from the carrier signal generator on the basis of the pre-encoded address information supplied from the address generator, and supplies a resultant MSK modulation signal to a wobbling unit. In step S3, the wobbling unit forms, on the optical disc, a spiral groove wobbled adaptively to the MSK modulation signal supplied from the modulator. In this optical disc, a given address can be accessed quickly and accurately.
