Laminated semiconductor ceramic capacitor with varistor function and method for manufacturing the same
A component body is obtained by alternately laminating and sintering a plurality of semiconductor ceramic layers formed of a SrTiO.sub.3-based grain boundary insulated semiconductor ceramic and a plurality of internal electrode layers. The average grain diameter of crystal grains is 1.0 ∝m or less and a coefficient of variation representing variations in a grain diameter of the crystal grains is 30% or less. To prepare the semiconductor ceramic an Sr compound, a Ti compound and a donor compound are weighed in predetermined amounts and mixed/pulverized. A calcined powder is prepared and a dispersant is added with an acceptor compound to the calcined powder. The resulting mixture is wet-mixed and a heat-treated powder is prepared. The heat-treated powder is formed into slurry and subjected to a filter treatment. The filtered slurry is used to prepare a semiconductor ceramic. The resulting laminated semiconductor ceramic capacitor has a varistor function having excellent durability, which can suppress a reduction of insulating properties and ensure desired electrical characteristics even when ESD occurs repeatedly.

MULTILAYER ELECTRONIC COMPONENT PRODUCTION METHOD
A sintered body that includes semiconductor ceramic layers and an internal electrode which are alternately stacked on one another is prepared. A first external electrode is formed on a side surface of the sintered body such that the first external electrode is connected to the internal electrode. An insulating layer is formed on a surface of the sintered body by applying a glass coating over an entire of the sintered body having the formed first external electrode. The insulating layer is exposed from the first external electrode. A second external electrode is formed on the first external electrode. This method provides the produced multilayer electronic component with a stable electric connection between the internal electrodes and the external electrodes.
