  • Patent number: 11289363
    Abstract: A method of manufacturing a semiconductor device includes: providing a substrate, forming a first opening, forming a first insulating layer, forming a second opening, embedding a conductive layer, forming a protective layer, and performing CMP. The substrate includes a semiconductor substrate and a semiconducting layer. The conductive layer is embedded in the second opening so that a gap along a thickness direction of the semiconducting layer is formed. The protective layer is formed in the second opening on at least a portion of a surfaces of the conductive layer. In the CMP step, a portion of the conductive layers formed outside the second opening is removed.

  • Patent number: 9960075
    Abstract: Using an STI insulating film in a high breakdown voltage MOSFET leads to deterioration in reliability due to impact ionization near the bottom corner of a drain isolation insulating film. The invention provides a method of manufacturing a semiconductor integrated circuit device including forming a hard mask film, an opening therein, and a sidewall insulating film on the side surface thereof; forming a shallow trench in the opening with the hard mask film as a mask and oxidizing at least an exposed portion; filling the trench with an insulating film and then removing it so as to leave it outside the trench in the opening and thereby forming a drain offset STI insulating film inside and outside the trench; and forming a gate electrode extending from the upper portion of a gate insulating film in an active region contiguous thereto to the upper portion of the drain offset insulating film.

  • Patent number: 9022710
    Abstract: Provided is a nut into which a bolt (10) including a male-threaded portion with a male-threaded external diameter d and a male-threaded core diameter d1 is screwed, wherein a bolt insertion side end of a female-threaded portion (21) formed in a nut body (20) is provided with an incompletely threaded female portion (22) that is formed by one to three pitches so that an internal diameter dimension D is larger than (d+d1)/2 and is smaller than the male-threaded external diameter d. Accordingly, even when the bolt is screwed into the nut in the inclination direction, the bolt may be rotated about a contact surface with respect to the incompletely threaded female portion (22), and hence seizing may be prevented.
