  • Patent number: 10319634
    Abstract: A semiconductor device that provides a pad electrically connected to the metal layer and a capacitor connected to the pad is disclosed. The semiconductor device provides an insulating film between the lower electrode of the capacitor and the pad. Because the insulating film protects and isolates the lower electrode from etching of the substrate via and deposition of the via metal, the lower electrode avoids voids or vacancies during formation of the via and the via metal.

  • Patent number: 10312125
    Abstract: A protective tape that improves solder bonding properties and reduces wafer warping. The protective tape includes, in the following order, an adhesive agent layer, a first thermoplastic resin layer, a second thermoplastic resin layer, and a matrix film layer. The protective tape satisfies the conditions expressed by the following formulae (1) to (3): Ga>Gb??(1) Ta<Tb??(2) (Ga*Ta+Gb*Tb)/(Ta+Tb)?1.4E+06 Pa.??(3) Ga represents a shear storage modulus of the first thermoplastic resin layer at a pasting temperature at which the protective tape is pasted; Gb represents a shear storage modulus of the second thermoplastic resin layer at the pasting temperature at which the protective tape is pasted; Ta represents a thickness of the first thermoplastic resin layer; and Tb represents a thickness of the second thermoplastic resin layer.
