Title:
METHOD FOR PRODUCING MULTILAYER CERAMIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2024/009900
Kind Code:
A1
Abstract:
A method for producing a multilayer ceramic capacitor according to the present invention, the multilayer ceramic capacitor being provided with a capacitor main body (1) which is obtained by stacking a plurality of dielectric layers (2), a plurality of first internal electrodes (3) and a plurality of second internal electrodes (4), a first via conductor (5) which is provided within the capacitor main body (1) and is electrically connected to the plurality of first internal electrodes (3), and a second via conductor (6) which is provided within the capacitor main body (1) and is electrically connected to the plurality of second internal electrodes (4), comprises: a step for forming a first material layer which is formed of a first material for the purpose of forming the first via conductor (5) and the second via conductor (6); and a step for forming a second material layer which is positioned at an end of at least one of the first via conductor (5) and the second via conductor (6), while being formed of a second material that is different from the first material and contains, as a main component, any one of Sn, Sn-Ag, Sn-Bi, Sn-In, Sn-Ag-Cu and Au.
