Patent ID: 7547370

Claim:
A method for manufacturing a multilayer ceramic electronic element, comprising the steps of: preparing a composite sheet by sequential performance of the following steps in that order; a first step of applying ceramic slurry to a long base film using a die coater for forming a ceramic green sheet; a second step of applying conductive paste to an upper surface of the ceramic green sheet by gravure printing using a plurality of conveying rollers, a pressure roller, and a gravure roller, for forming internal electrodes; a third step of drying or semi-drying the internal electrodes a fourth step of applying a step-smoothing ceramic paste to the upper surface of the ceramic green sheet in a region in which the internal electrodes are not formed by gravure printing using a plurality of conveying rollers, a pressure roller, and a gravure roller; and a fifth step of drying the step-smoothing ceramic paste; a sixth step of applying ceramic slurry to the internal electrodes and the dried ceramic paste using a die coater for forming another ceramic green sheet; a seventh step of applying conductive paste to an upper surface of the another ceramic green sheet by gravure printing using a plurality of conveying rollers, a pressure roller, and a gravure roller, for forming the internal electrodes; an eighth step of drying or semi-drying the internal electrodes a ninth step of applying the step-smoothing ceramic paste to the upper surface of the another ceramic green sheet in a region in which the internal electrodes are not formed by gravure printing using a plurality of conveying rollers, a pressure roller, and a gravure roller; and a tenth step of drying the step-smoothing ceramic paste; the sixth to tenth steps being performed at least once; forming a laminate body by laminating a plurality of the composite sheets to each other; sintering the laminate body to form a sintered body; and forming external electrodes electrically connected to the respective internal electrodes on an external surface of the sintered body.
