Patent ID: 10971305

Abstract:
A method for manufacturing a ceramic electronic component in which a plated electrode can be formed in a region of the surface of a ceramic base body formed of a titanium-containing metal oxide. The method includes preparing a ceramic base body containing a titanium-containing metal oxide, forming a low-resistance section by modifying the metal oxide through irradiation of part of a surface layer portion of the ceramic base body with a pulse laser with a peak power density of 1×106 W/cm2 to 1×109 W/cm2 and a frequency of 500 kHz or less, and forming an electrode on the low-resistance section by electroplating. The laser irradiation generates an O defect in a titanium-containing metal oxide, such as BaTiO3 to form an n-type semiconductor. Since this semiconductor section has a lower resistance value than the metal oxide, plating metal can be selectively deposited by electroplating.
