  • Patent number: 8755167
    Abstract: There are provided a ceramic sheet product for a ceramic electronic component, a multilayer ceramic electronic component using the same, and a method of manufacturing the multilayer ceramic electronic component. The ceramic sheet product for a ceramic electronic component includes a ceramic layer; a metal layer formed on the ceramic layer; and metal nanostructures contacting the metal layer and protruding from the metal layer to an inner portion of the ceramic layer. With the multilayer ceramic electronic component using the ceramic sheet product for a ceramic electronic component, an interval between electrodes is reduced to thereby allow for the increase of capacitance, whereby a multilayer ceramic electronic component having high capacitance may be provided.

  • Publication number: 20130038982
    Abstract: Disclosed herein are a multilayer ceramic condenser and a method for manufacturing the same. The multilayer ceramic condenser includes inner metal electrode layers formed within a magnetic layer, and conductive layers each formed between the inner metal electrode layers, and a method for manufacturing the same. According to the present invention, a contact between the inner metal electrode layers in the multilayer ceramic condenser can be prevented, thereby reducing the manufacturing loss due to occurrence of short circuits and improving thermal stability, by forming an ultrathin conducting layer with a thickness of about 10 nm or less between the inner metal electrode layers. Therefore, the multilayer ceramic condenser can be ensured to have excellent reliability to meet the demands of markets requesting a high-capacity multilayer ceramic condenser (MLCC) having high performance, small size, and light weight.
