Patent ID: 8609522

Claim:
A process for producing a conducting electrode on a substrate comprising: depositing a layer made with a dielectric material; depositing, on the dielectric layer, a protective layer made of a nitride of a metal; depositing a functionalization layer made of a material comprising a chemical species such that the free enthalpy of formation of a nitride of said species is less, in absolute value, than the free enthalpy of formation of the nitride of the metal of said protective layer over a temperature range of between 0and 1200° C., said chemical species being chosen from among the following species: Mg or Ca; annealing an assembly comprising said protective layer and said functionalization layer such that the chemical species at least partially diffuse from said functionalization layer into said protective layer and nitrogen atoms at least partially migrate from said protective layer into said functionalization layer, said conducting electrode including said protective and functionalization layers after annealing.
