摘要： Conventionally, electrostrictive effect elements have been obtained as follows. A laminated body in which every other internal electrodes are connected alternately with one of two external electrodes which are formed on opposed faces of the body, is set in a plating bath. Metal ions in the bath are deposited on the internal electrodes. After insulating films are formed, the insulating material only on the deposited metals are removed until the deposited metals are exposed, and the laminated body is cut. However, there are the problems, for example, the electrical conduction is not attained because of the oxidation of the deposited metals when the element is left at a high temperature. The solutions of the problems are found in this invention. Electrostrictive effect layers and internal electrodes are laminated alternately. The end faces of the every other internal electrodes are exposed on the opposed side faces respectively. Temporary external electrodes are formed on the exposed end faces of the internal electrodes. Metallic protrusions are formed on the end faces of the exposed internal electrodes by the electric plating using the temporary external electrodes as cathodes. Then, by mechanical machining or the like, the parts between the metallic protrusions (the parts being not plated) are removed to form recessed parts. Thereafter, insulating films are formed in the recessed parts. Then, by removing the insulating films through polishing to the depth until the metallic protruding parts are eliminated, the every other internal electrodes are made to be exposed or the metallic protruding parts are made to be exposed. In those places, external electrodes are formed, and the every other internal electrodes can be connected to the external electrodes. According to this invention, since the interfacial distances between the end parts of the internal electrodes having different potentials can be increased substantially, electrostrictive elements of high insulation reliability can be realized.

摘要： PURPOSE:To prevent the influence of a resist surface layer which is hard to dissolve, and form a resist pattern highly conformable to a designed pattern, by adding a process exposing the resist surface to an acid atmosphere after exposure to light and before baking, and dissolving the whole resist surface as far as a specified depth in a developing process. CONSTITUTION:In order to supplement acid which is insufficient in the vicinity of a resist surface of a silicon substrate coated with a resist layer 2, the laver is spin-coated with solution wherein acetic acid is diluted to 10% with pure water, thereby obtaining an acid supplement layer 3. Then selective exposure to light is performed by using KrF excimer layer 4, arud acid 5 is generated. After the exposure to light, baking is performed at 110 deg.C for 2 minutes. Hence the acid supplement layer 3 on the resist surface, and high-molecular dissolution inhibiter THP-M in the part of the resist where acid is selectively generated are decomposed, and dissolution inhibiting effect is reduced. Then a developing process is performed. The acid supplement layer 3 on the resist surface is dissolved, and a resist pattern 7 can be obtained.

摘要： PURPOSE:To provide an electrostructive effect element which allows an inside electrode to be connected with an outside electrode with high reliability based on the application of plating technology. CONSTITUTION:Electrostructive materials 1 and 2 and inside electrodes 3 and 4 are laminated alternately so as to prepare a laminated body which has two planes where the end of every inside electrode is exposed and two planes where every other inside electrodes are exposed. There are formed temporary outside electrodes 9 and 10 on the two planes where the inside electrodes are exposed on every other of this laminated body. The edges of the inside electrodes are plated on every other layer. Then, insulation layers 7 and 8 are formed on the unplated portions. Then, the insulation layers are partially eliminated so as to expose the plating metal. After the plating metal is removed by melting, the outside electrodes are coated so that the inside electrodes may be connected with the outside electrodes. Since the oxidation of the plating metal in heat treatment during the formation of the outside electrodes disappears by removing the plating metal, the inside electrodes can be connected with the outside electrodes with high reliability.
