IPC: H01L41/22
Filed: 1992-09-24
Abstract: PURPOSE:To prevent the intrusion of mositure into a multilayer piezoelectric element by depositing a metal by plating on every other layer of exposed parts of the internal electrodes exposed of the multilayer body of the element on the surface of the multilayer body where no external electrode is provided and sintering a moisture resisting insulator on the surface of the multilayer body on the element side by performing a specific process thereafter. CONSTITUTION:The facing side faces without temporarily installed external electrodes of a multilayer body are plated after one of the side faces is masked with a masking material. As a result, belt-like deposited metal films 5 of plated nickel having heights of 30mum and widths of 50mum are formed on every other internal electrode. Then an insulating material 7 is applied to the two nickel- plated surfaces to a uniform thickness and baked. The application of the insulating material is performed by screen printing with glass paste. The deposited metal films 5 are removed from the exposed part of the multilayer body by electrolytic etching. Since electrodes having the same polarity are not exposed on one side face of the multilayer body, the deterioration of electrical insulation of the multilayer body due to the adhesion of moisture does not occur. Therefore, a highly reliable multilayer piezoelectric element can be supplied.
