ABSTRACT:
To reduce the proportion of rejects resulting by reasons of short circuits in the manufacture and use of miniaturized multilayer circuits and to improve the electric efficiency, there is inserted between each conductive layer of low resistance and each insulating layer of high thermal stability, a very thin layer of a conductive material, preferably non-magnetic, of high resistivity and of crystallographic reference at least compatible with respect to the first conductive material and of low or negligible thermal expansion in the range of temperatures to which the circuits are submitted both during manufacture and use.
