  • Patent number: 9251958
    Abstract: When a monolithic ceramic electronic component is viewed from either one of end surfaces thereof, an outer electrode includes a solder-repellent portion and a solder-receivable portion. The solder-repellent portion covers the central portion of an end surface of a ceramic laminate body. The solder-receivable portion includes portions disposed on two opposing sides of the solder-repellent portion. When the monolithic ceramic electronic component is mounted on the circuit board, solder does not adhere to a portion around the central portion of the end surface. Thus, expansion and contraction that occur as a result of application of an AC voltage are not significantly transmitted to the circuit board. Consequently, vibrations of the circuit board are reduced.

    Abstract: A thin sub-layer (<15 ?) of an impurity is formed under, over, or inside a thicker layer (˜30-100 ?) of a high-k (k>12) host material. The sub-layer may be formed by atomic layer deposition (ALD). The layer and sub-layer are annealed to form a composite dielectric layer. The host material crystallizes, but the crystalline lattice and grain boundaries are disrupted near the impurity sub-layer, impeding the migration of electrons. The impurity may be a material with a lower dielectric constant than the high-k material, added in such a small relative amount that the composite dielectric is still high-k. Metal-insulator-metal capacitors may be fabricated by forming the composite dielectric layer between two electrodes.

    Abstract: A laminated ceramic capacitor is characterized in that when the section constituted by two internal electrode layers positioned adjacent to each other in the laminating direction and one dielectric layer present between the two internal electrode layers is considered a unit capacitor, then the respective capacitances of the unit capacitors arranged in the laminating direction are distributed in such a way the capacitance at the center in the laminating direction is lower than the capacitances at both ends in the laminating direction. The laminated ceramic capacitor is resistant to deterioration of insulation resistance.
