  • Magnetic tunnel junction device, method for manufacturing magnetic tunnel junction device, and magnetic memory
    Patent number: 11963458
    Abstract: Provided are a magnetic tunnel junction dement suppressing diffusion and penetration of constituent elements between a hard mask film, and a magnetic tunnel junction film and a protection layer, and a method for manufacturing the magnetic tunnel junction element. The magnetic tunnel junction element has a configuration in which a non-magnetic insertion layer (7) including Ta or the like is inserted beneath a hard mask layer (8).

  • Piezoelectric device and package thereof
    Patent number: 6541897
    Abstract: A package for a piezoelectric resonator, includes an insulating base that has a rectangular box shape and made of laminated thin ceramics sheets, and a lid that is made of a thin rectangular sheet of transparent glass material and bonded on the top surface of the base. A tuning fork type quartz crystal resonator element is hermetically sealed in the package. The corners of the lid are cut off diagonally at an angle of approximately 45 degrees or rounded so as to correspond to the cutouts of quarter circles at the corners of the base that result from via holes for wiring inside the base. A predetermined sealing width on the top surface of the base between the lid and the inner periphery of the base and a sufficient margin width between the periphery of the lid and the outer periphery of the base are ensured at the corners.
