Abstract

1,149,569. Capacitors. MINISTER OF TECHNOLOGY. 31 Aug., 1967 [1 Sept., 1966], No. 39007/66. Heading H1M. A capacitor comprises a pair of coplanar electrodes 1, 2 on a dielectric substrate 3, the electrodes having interdigitated projections 5, 6, 7 and 8, and a dielectric overlayer which fills the space 4 between the projections (Figs. 3, 4, not shown), the useful capacitance being derived from the proximity of the edges of the projections. The capacitance may be further increased by another parallel connected pair of electrodes on the overlayer (Fig. 5, not shown). The substrate and overlayer dielectric may be glass, ceramic, alumina, barium titanate, lead titanate zirconate or silicon monoxide and may be selected so that its change of dielectric constant with temperature compensates for its thermal expansion. To form the electrodes a single conductive layer of, e.g. tantalum may be applied and divided by a meandering slot by electron beam treatment or a masking and etching process. Alternatively the electrodes may be printed separately. The capacitance may be trimmed to a desired value by electron beam treatment, or anodizing, or etching.
