Abstract
Improved copper conductor inks useful in fabricating multilevel circuits are provided. The inks comprise copper powder, a novel zinc-aluminum-lead-borosilicate glass frit, bismuth oxide and a suitable organic vehicle. The inks are advantageous in that the films formed therefrom are oxidation resistant and have a reduced tendency for flux components to leach into adjacent dielectric films.
