Embodiment Construction

[0023] Hereinafter, embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. In the drawings, the shape and size of components may be exaggerated or reduced for clarity.

[0024] However, the present disclosure may be implemented in different forms, and should not be construed as being limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0025] Throughout the specification, it will be understood that when an element such as a layer, region, or wafer (substrate) is described as being "on", "connected to" or "bonded to" another element When an element is used, it can be directly "on", "connected to" or "coupled to" another element, or there may be other elements between them. In contrast, when an element is referred to as being "directly on", "directly...

Abstract

A multilayer ceramic capacitor includes a body including first and second internal electrodes facing each other with respective dielectric layers interposed therebetween, and first and second externalelectrodes disposed on an external surface of the body and electrically connected to the first and second internal electrodes, respectively. Each of the first and second external electrodes includesa first electrode layer containing any one selected from the group consisting of TiW, TiN, and TaN, or a combination thereof, and a second electrode layer disposed on the first electrode layer.

Description

[0001] This application requires a Korean patent application No. 10-2017-0042905 filed at the Korean Intellectual Property Office on April 3, 2017 and a Korean patent application No. 10-2017-0088853 filed at the Korean Intellectual Property Office on July 13, 2017. Korea The priority of the patent application, the disclosure of the Korean patent application is incorporated herein by reference in its entirety. Technical field [0002] The present disclosure relates to a multilayer ceramic capacitor and a method of manufacturing the same. Background technique [0003] In accordance with the trend toward miniaturization and high capacitance of multilayer ceramic capacitors (MLCC), the importance of increasing the effective volume ratio (the ratio of the volume that contributes to the capacitance to the total volume) of the multilayer ceramic capacitor has increased. [0004] As a method of increasing the effective volume ratio, a method of performing cutting to expose the internal elec...
