Le trifluorure d'azote est utilisé pour la gravure ionique réactive des wafers en silicium. Le NF3 y est décomposé in situ en azote et fluor, et les radicaux fluor obtenus agissent comme des agents nettoyants qui attaquent le silicium. Il peut être aussi utilisé avec le nitrure de silicium, le siliciure de tungstène, et le tungstène produits par dépôt chimique en phase vapeur. Dans toutes ces applications, le NF3 a été choisi vers l'an 2000 comme substitut plus protecteur pour l'environne… barbara peressoni
