  • Patent number: 9343298
    Abstract: The disclosure provides a method for producing a stack of layers on a semiconductor substrate. The method includes producing a substrate a first conductive layer; and producing by ALD a sub-stack of layers on said conductive layer, at least one of said layers of the sub-stack being a TiO2 layer, the other layers of the sub-stack being layers of a dielectric material having a composition suitable to form a cubic perovskite phase upon crystallization of said sub-stack of layers. Crystallization is obtained via heat treatment. When used in a metal-insulator-metal capacitor, the stack of layers can provide improved characteristics as a consequence of the TiO2 layer being present in the sub-stack.

  • Patent number: 9330842
    Abstract: In a monolithic ceramic electronic component, given that an interval between outer-layer dummy conductors adjacent to each other in an outer layer portion is d1, and that an interval between first and second inner electrodes adjacent to each other in an inner layer portion is d2, 1.7d2?d1 is satisfied. By reducing a density of the outer-layer dummy conductors in the outer layer portion on that condition, pressing of the inner electrodes through the outer-layer dummy conductors is relieved in a pressing step before firing. As a result, a distance between the inner electrodes can be prevented from being locally shortened. It is hence possible to effectively reduce and prevent degradation of reliability of the monolithic ceramic electronic component, e.g., a reduction of BDV.
