  • Capacitor comprising bis(4-mercaptophenyl) sulfide derivative
    Patent number: 7006344
    Abstract: The present invention provides a bis(4-mercaptophenyl) sulfide derivative represented by general formula 1. This derivative is a monomer that can form a dielectric film suitable for an electronic component. The present invention further provides a method for producing this derivative and an electronic component having high characteristics under excellent humidity and high temperature.

  • Capacitor and manufacturing method thereof
    Patent number: 6762107
    Abstract: A capacitor (1) using a flexible substrate (2) includes a hole portion (6a) formed in a dielectric (6) to connect an upper electrode (7) to an external leader electrode (4). At least part of the hole portion (6a) extends from its lower end to upper end at an inclination between 0.1 and 20° with respect to a top surface of the external leader electrode (4). Then, an upper end corner of an inclined wall surface of the upper electrode (7), which inclines along the hole portion (6a) of the dielectric (6), has a downward inclination between 0.1 and 20°. A lower end corner of the inclined wall surface of the upper electrode (7), which inclines along the hole portion of the dielectric (6), has an upward inclination between 0.1 and 20°. As a result, stress concentration on the corners of the upper electrode (7) is drastically reduced to prevent the upper electrode (7) from cracking.
