  • Multilayer ceramic electronic component
    Patent number: 11094468
    Abstract: A multilayer ceramic electronic component includes a ceramic body including dielectric layers and first and second internal electrodes alternately laminated with respective dielectric layers disposed therebetween to be exposed to first and second external surfaces of the ceramic body, and first and second external electrodes disposed on the first and second external surfaces of the ceramic body and connected to corresponding internal electrodes, among the first and second internal electrodes, respectively. The dielectric layer includes a portion, disposed between the first and second external electrodes, having a thickness of 3.5 micrometers or more to 3.7 micrometers or less.
    Type: Grant
    Filed: January 23, 2019
    Date of Patent: August 17, 2021
    Assignee: SAMSUNG ELECTRO-MECHANICS CO., LTD.

  • Capacitor component and method for manufacturing the same
    Patent number: 11062847
    Abstract: A method for manufacturing a capacitor component includes an operation of sintering under a moderately-or-more reducing atmosphere for hydrogen, a body in which a plurality of dielectric layers having internal electrodes printed thereon are laminated,; a first reoxidation operation of subjecting the sintered body to a first reoxidation heat treatment under an oxidizing atmosphere; and a second reoxidation operation of subjecting the body having undergone the first reoxidation heat treatment to a second reoxidation heat treatment under an oxidizing atmosphere.
