发明名称 Method of producing ceramic laminates, laminated electronic parts and method of producing the same
摘要 A method of producing ceramic laminates comprising the steps of forming a ceramic green sheet by applying a ceramic slurry onto a carrier film; forming, maintaining a predetermined gap, a plurality of electrically conducting patterns having inclined surfaces at the ends thereof by printing an electrically conducting paste onto the main surface of said ceramic green sheet; forming ceramic patterns having inclined surfaces at the ends thereof among said electrically conducting patterns by printing a ceramic paste maintaining a distance of not smaller than 10 mum from said electrically conducting patterns; and laminating ceramic green sheets on which are formed said electrically conducting patterns and said ceramic patterns. A method of producing ceramic laminates comprising the steps of forming a plurality of electrically conducting patterns maintaining a predetermined distance on the main surface of a ceramic green sheet by printing an electrically conducting paste thereon; forming an organic resin film on the upper surface of the ceramic green sheet among said electrically conducting patterns and on the upper surfaces of said electrically conducting patterns in the vicinities thereof; forming ceramic patterns on said organic resin film among said electrically conducting patterns by applying a ceramic paste thereon; forming a temporarily laminated article by laminating a plurality of ceramic green sheets on which said electrically conducting patterned said organic resin film and said ceramic patterns are formed; and forming a laminate by pressing said temporarily laminated article while heating it at a temperature at which said organic resin film melts. A laminated electronic part in which non-capacity portions constituted by dielectric ceramic layers and inner electrode layer-extending portions formed by extending inner electrode layers, are formed integrally on the side surfaces of a capacity portion constituted by alternately laminating the dielectric ceramic layers and the inner electrode layers; and a pair of outer electrodes are provided for said non-capacity portions so that said inner electrode layer-extending portions are alternately conducted thereto; wherein said inner electrode layers and said inner electrode layer-extending portions are forming a flush surface without substantially a difference in level, and the dielectric ceramic layers in said non-capacity portions are constituted by ceramics which can be more highly sintered than the dielectric ceramic layers in said capacity portion; and a method of producing the laminated electronic parts. Even when the number of the layers is increased by decreasing the thickness of the layers, a difference in level is not created by the thickness of the electrically conducting patterns, suppressing the ceramic laminate from being deformed and suppressing a drop in the insulating resistance and the occurrence of short-circuit.
