Array type multi-layer ceramic capacitor and production method thereof

Abstract

A method of producing an array type multi-layer ceramic capacitor is disclosed, comprising: forming dielectric films, forming dielectric sheets on which internal electrodes and interelectrode dielectrics formed on the same plane as the internal electrodes are printed simultaneously by spraying ink intended for internal electrodes and ink intended for dielectrics onto the dielectric film via a plurality of inkjet printer heads, stacking and compressing the dielectric sheets, cutting the stacked dielectric sheet to include a plurality of internal electrodes on the same plane as the dielectric sheet, and sintering the cut dielectric sheets. The array type multi-layer ceramic capacitor according to the invention can solve the problem of interlayer gaps by printing the dielectrics and internal electrodes simultaneously, and can solve the contact problem by printing the internal electrode and the external electrode as a single body.

An array type multi-layer ceramic capacitor comprising a plurality of dielectric sheets on each of which are printed a first external electrode, a dielectric joined to the first external electrode and subsided with a face thereof exposed, an internal electrode formed in the subsided portion of the dielectric, and a second external electrode formed to join as a single body with the internal electrode,
 wherein the first external electrode, the internal electrode, and the second external electrode are aligned in preconfigured numbers and in predetermined intervals, and the dielectric sheets are stacked alternately so that the first external electrodes and the second external electrodes are symmetrical and thus electrically connected with each other.   
   
   
       2 . The array type multi-layer ceramic capacitor as set forth in  claim 1 , wherein the first external electrode, the internal electrode, and the second external electrode are printed simultaneously by an inkjet technique. 
   
   
       3 . The array type multi-layer ceramic capacitor as set forth in  claim 2 , wherein the inkjet technique is a technique of spraying ink intended for electrodes and ink intended for dielectrics using a plurality of inkjet printer heads. 
   
   
       4 . The array type multi-layer ceramic capacitor as set forth in  claim 1 , wherein the first external electrode, the internal electrode, and the second external electrode are formed with different types of material. 
   
   
       5 . The array type multi-layer ceramic capacitor as set forth in  claim 1 , wherein the number of internal electrodes included in the same plane as the dielectric sheet is two or four.
