Ceramic electronic component and method of manufacturing the same

A multilayer electronic component includes a body including a dielectric layer and internal electrodes alternately stacked with the dielectric layer interposed therebetween, and an external electrode disposed on the body and connected to the internal electrodes . An end portion of at least one of the internal electrodes in a longitudinal direction of the body is thicker than a central portion of the internal electrode, and a ratio t/tof a thickness tof the end portion to a thickness tof the central portion satisfies 1.1&#x2264;t/t&#x2264;1.5.

Multilayer electronic component

A capacitor component includes a porous body, a first electrode layer covering surfaces of pores of the porous body, a dielectric layer covering the first electrode layer, and a second electrode layer filling the pores of the porous body and covering the dielectric layer.

Capacitor component

Provided is a capacitor including a substrate including first and second trenches spaced apart from each other, a first electrode disposed in the first trench and one surface of the substrate, a second electrode disposed in the second trench and on the one surface of the substrate and spaced apart from the first electrode, first and second pad electrodes arranged on the first and second electrodes, respectively, and a passivation layer disposed on the first and second pad electrodes and having openings partially exposing the first and second pad electrodes, respectively.

Capacitor and method of manufacturing the same

A thin film capacitor includes a body including alternately stacked first and second electrode layers and dielectric layers on a substrate, the second electrode layer including a second lower electrode layer and a second upper electrode layer formed on the second lower electrode layer, the second lower electrode layer including a material having a higher band gap energy than the first electrode layer and the second upper electrode layer.

Thin film capacitor

A thin-film ceramic capacitor includes: a body in which a plurality of dielectric layers and first and second electrode layers are alternately disposed on a substrate; and first and second electrode pads disposed on an external surface of the body. The dielectric layer contains a mixed phase of a perovskite phase having ferroelectric properties and a pyrochlore phase having paraelectric properties, the pyrochlore phase being disposed on interfaces between the dielectric layers and the first and second electrode layers in lower portions of the dielectric layers.

Thin-film ceramic capacitor

Disclosed herein is a method of qualitatively analyzing high-molecular additives in a metal plating solution, including: removing sulfate ions and metal ions from a metal plating solution; and qualitatively analyzing the metal plating solution, from which sulfate ions and metal ions are removed, using Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight Mass Spectroscopy (MALDI-TOF MS). The method is advantageous in that the structure and molecular weight of high-molecular additives present in very small amounts in a plating solution can be accurately measured while maintaining the specific structure and molecular weight thereof without degrading the high-molecular additives.
