ABSTRACT:
Thin-film microcircuit structures passivated with silicon nitride are provided in which included electrical components containing nickel, chromium or other nitride-forming metals are encapsulated in an oxide material, preferably silicon oxide. The metal-containing components are thus prevented from reacting with the silicon nitride passivation coating during through-passivation laser trimming of the components.
