Multi layer ceramic capacitor, embedded board using multi layer ceramic capacitor and manufacturing method thereof

摘要

A multilayer ceramic capacitor includes a multilayer ceramic sintering body and one or two or more internal electrode units formed to be placed inside the multilayer ceramic sintering body. Each internal electrode unit includes first internal electrodes formed in the multilayer ceramic sintering body in such a way to be spaced apart from each other, one or more of both ends of one side of each of the first internal electrodes being formed to be exposed to the top or bottom surface of the multilayer ceramic sintering body, and second internal electrodes placed between the first internal electrodes, respectively, and formed in the multilayer ceramic sintering body in such a way to be spaced apart from each other, one or more of both ends of the other side of each of the second internal electrodes being formed to be exposed to the top or bottom surface of the sintering body.

主权项

1. A multilayer ceramic capacitor, comprising:
a multilayer ceramic sintering body; and a first internal electrode unit, a second internal electrode unit and a third internal electrode unit formed to be vertically placed inside the multilayer ceramic sintering body, wherein the first internal electrode unit, the second internal electrode unit and the third internal electrode unit are formed in such a way as to be spaced apart from each other and sequentially stacked, the first internal electrode unit has a first area, the second internal electrode unit has a second area smaller than the first area, and the third internal electrode unit has a third area smaller than the second area, wherein each of the first internal electrode unit, the second internal electrode unit and the third internal electrode unit comprises: a first internal electrode having a sheet form, one end of a first side of the first internal electrode being formed to be exposed to a top surface of the multilayer ceramic sintering body, the other end of the first side thereof being formed to be exposed to a bottom surface of the multilayer ceramic sintering body, and the top surface being vertically opposite to the bottom surface, and a second internal electrode having a sheet form, one end of a second side of the second internal electrode being formed to be exposed to the top surface of the multilayer ceramic sintering body, and the other end of the second side thereof being formed to be exposed to the bottom surface of the multilayer ceramic sintering body, the second side being opposite to the first side.
