摘要: Improved copper conductor inks useful in the fabrication of multilevel circuits are disclosed. The inks comprise copper powder, a devitrifying glass frit selected from a zinc-calcium-aluminum-silicate glass frit, a zinc-magnesium-barium-aluminum-silicate glass frit and mixtures thereof, an adhesion promoting oxide, and a suitable organic vehicle. These inks are particularly adapted for applications where superior adhesion between the copper conductor ink and the underlying substrate or dielectric film is required.

摘要: Improved copper conductor inks useful in fabricating multilevel circuits are provided. The inks comprise copper powder, a devitrifying glass frit which does not begin to flow until the furnace temperature is above about 700.degree. C., and a suitable organic vehicle. Devitrifying glass frits with these properties include a zinc-calcium-aluminum-silicate glass frit, a zinc-magnesium-barium-aluminum-silicate glass frit, a zinc-magnesium-barium-aluminum-zirconium-phosphosilicate glass frit and mixtures thereof. The inks are advantageous in that they form copper conductor layers having excellent properties without the inclusion of traditional flux materials such as bismuth oxide.

摘要: 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.

摘要: A novel devitrifying frit is disclosed which has a coefficient of expansion essentially the same as that of silicon. The subject frits have a high softening temperature and excellent reheat stability which make them useful in ink formulations for forming dielectric layers in multilayer circuitry. The frits are also suitable for use as a substrate material for direct mounting of silicon chips or for use in thick film via-fill inks.
