One capacitor fabrication process including metal layer forming a metal layer on one surface of a substrate, dielectric layer forming a dielectric layer on the metal layer, metal foil forming a metal foil on the dielectric layer, separating the noble metal layer from the dielectric layer, and electrode layer forming an electrode layer on the second surface of the dielectric layer, wherein the second surface faces away from the first surface of the dielectric layer with the metal foil. Another capacitor fabrication process includes separation layer forming a separation layer on one surface of a substrate, dielectric layer forming a dielectric layer on the separation layer, metal foil forming a metal foil the dielectric layer, separating the substrate from the separation layer, and an electrode layer forming an electrode layer on the second surface of the dielectric layer, wherein the second surface faces away from the first surface of said dielectric layer with the metal foil. A thin-film capacitor has higher capacity, is so slimmed down and has a form well fit for being buried in a base board, and can be used even at high frequencies.

Method of manufacturing capacitor

A capacitor comprises: a lower electrode formed of a foil made of a polycrystalline metal; an upper conductor layer; and a dielectric layer disposed between the lower electrode and the upper electrode layer. Grain boundaries of the polycrystalline metal appear at the top surface of the lower electrode. The capacitor further comprises an insulator that is disposed between the top surface of the dielectric layer and the bottom surface of the upper electrode layer and that is present only in part of a region in which the top surface of the dielectric layer and the bottom surface of the upper electrode layer face each other. The insulator is disposed to cover at least part of the grain boundaries appearing at the top surface of the lower electrode when seen from above the top surface of the dielectric layer. The insulator is formed by electrophoresis.

A screen display apparatus is capable of visually presenting to a viewer E a secondary image (virtual image and/or a real image) as an &ldquo;inclined&rdquo; a primary image (subject) and is vertically inclined with respect to said viewer at a position, which is different from a position of said primary image This is realized through an action of a lens With the &ldquo;inclination, the viewer E views the secondary image with a three-dimensional feeling. The &ldquo;inclination&rdquo; is effective when the upper part of the secondary image is located farther from the viewer E than the lower part thereof, and when its angle &thgr; is within a range of 3&deg; to 40&deg;. Further, a screen display apparatus, a plurality of secondary images (in the figures, virtual images and ) on a primary image as a subject are formed by a microlens array including convex microlenses and concave microlenses The screen display apparatus visually presents those secondary images to a viewer E so that those images are viewed as a single image. As a result, an image is displayed with an intensive three-dimensionally feeling.
