Passive ceramic device

摘要

A ceramic passive component has a metal, alloy or conductive oxide barrier layer (4, 6) between a dielectric (5) and one or each of two electrodes (3, 7). A ceramic passive component has a barrier layer (4, 6) which is located between a dielectric (5) and one or each of two electrodes (3, 7) and which comprises TixWy, Cr, CrxOy, Nb, Ta, Ti, W, NixNby, NixMoy, IrxTay, IrxZry, FexWy, WxSiy, PtxSiy, TaxSiyNz, TixSiyNz, MoxSiyNz, CoxSiy, CrxSiy, CrxSiyNz, CrxSiyOz, TixNy, WxNy, TixWyNz, HfxNy, TaxNy, RuxOy, MoxOy, IrxOy and/or NixCryAlz, where x = 0 to 1, y = 0 to 1 and z = 0 to 1.
