Abstract

De façon à par exemple améliorer le contact ohmique entre deux pièces métalliques (10, 20) situées à un niveau de métallisation (M3), on équipe ces deux pièces de deux vias déportés (101, 201) situés au niveau de métallisation (M3) et au moins partiellement au niveau de vias (V3) immédiatement supérieur. Chaque via déporté comporte par exemple un composé inoxydable ou quasi inoxydable tel qu'une couche barrière en Ti/TiN.
