  A process is disclosed of producing on a crystalline silicon substrate a barrier layer triad capable of protecting a rare earth alkaline earth copper oxide conductive coating from direct interaction with the substrate. A silica layer of at least 2000 .ANG. in thickness is deposited on the silicon substrate, and followed by deposition on the silica layer of a Group 4 heavy metal to form a layer having a thickness in the range of from 1500 to 3000 .ANG.. Heating the layers in the absence of a reactive atmosphere to permit oxygen migration from the silica layer forms a barrier layer triad consisting of a silica first triad layer located adjacent the silicon substrate, a heavy Group 4 metal oxide third triad layer remote from the silicon substrate, and a Group 4 heavy metal silicide second triad layer interposed between the first and third triad layers.

  A circuit element is disclosed comprised of a substrate and an electrically conductive layer located on the substrate. The electrically conductive layer is comprised of a crystalline rare earth alkaline earth copper oxide. The substrate is formed of a material which increases the electrical resistance of the conductive layer when in contact with the rare earth alkaline earth copper oxide during crystallization of the latter to an electrically conductive form. A barrier layer is interposed between the electrically conductive layer and the substrate. The barrier layer contains magnesium, a group IVA metal, or a platinum group metal, either in an elemental state or in the form of an oxide or silicide. The circuit element is produced by first forming the barrier layer on the substrate followed by coating conductor precursor metal-ligand compounds of each of rare earth, alkaline earth, and copper containing at least one thermally volatilizable ligand and heating the precursor metal-ligand compounds in the presence of oxygen to produce a crystalline rare earth alkaline earth copper oxide electrically conductive layer.
