Abstract
Official abstract text for this publication.
A method for manufacturing a multilayer ceramic capacitor including an operation of preparing a ceramic green sheet; an operation of forming a conductive paste on the ceramic green sheet; an operation of forming a ceramic laminate by stacking a ceramic green sheet on which the conductive paste is formed; an operation of sintering the ceramic laminate; and an operation of forming an external electrode on an exterior of the ceramic laminate, wherein the conductive paste includes a first mixture including a metal powder, a dispersant, and a hydrophobic solvent and a second mixture including a hydrophilic binder and a hydrophilic solvent, the conductive paste being an emulsion in which the first mixture is dispersed in the second mixture.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a multilayer ceramic capacitor, comprising: an operation of preparing a ceramic green sheet; an operation of forming a conductive paste on the ceramic green sheet; an operation of forming a ceramic laminate by stacking a ceramic green sheet on which the conductive paste is formed; an operation of sintering the ceramic laminate; and an operation of forming an external electrode on an exterior of the ceramic laminate, wherein the conductive paste includes a first mixture including a metal powder, a dispersant, and a hydrophobic solvent and a second mixture including a hydrophilic binder and a hydrophilic solvent, the conductive paste being an emulsion in which the first mixture is dispersed in the second mixture. 2. The method for manufacturing a multilayer ceramic capacitor of claim 1 , wherein a volume ratio of the first mixture to the second mixture is 1 or less. 3. The method for manufacturing a multilayer ceramic capacitor of claim 1 , wherein the first mixture particle has a diameter of 0.1 to 100 μm. 4. The method for manufacturing a multilayer ceramic capacitor of claim 1 , wherein a content of the dispersant in the first mixture is 0.01 wt % or more. 5. The method for manufacturing a multilayer ceramic capacitor of claim 1 , wherein the metal powder is at least one selected from a group consisting of Ni, Cu, Au, Ag, Pd, Pt, and alloys thereof. 6. The method for manufacturing a multilayer ceramic capacitor of claim 1 , wherein the dispersant includes one or more of a non-ionic surfactant, a cationic surfactant, and an anionic surfactant. 7. The method for manufacturing a multilayer ceramic capacitor of claim 1 , wherein the hydrophobic solvent includes one or more of an acetate-based solvent, a terpene-based solvent, a hydrocarbon-based solvent, a carboxylic acid-based solvent, and an ester-based solvent. 8. The method for manufacturing a multilayer ceramic capacitor of claim 1 , wherein the hydrophilic binder includes one or more of polyvinyl alcohol, cellulose, and a water-soluble acrylic resin. 9. The method for manufacturing a multilayer ceramic capacitor of claim 1 , wherein the hydrophilic solvent includes one or more of water and dimethyl sulfoxide.
