    Abstract: A plasma treatment method used to form improved PECVD silicon nitride film passivation layers over metal interconnections on ULSI circuits is achieved. The process is carried out in a single PECVD reactor. After depositing a thin silicon oxide stress-release layer over the metal lines, a plasma-enhanced CVD silicon nitride layer is deposited, and subsequently a plasma treatment step is carried out on the silicon nitride layer. The use of a sufficiently thin silicon nitride layer eliminates photoresist trapping at the next photoresist process step that would otherwise be trapped in the voids (keyholes) that typically form in the silicon nitride passivation layer between the closely spaced metal lines, and can cause corrosion of the metal. The plasma treatment in He, Ar, or a mixture of the two, is then used to densify the silicon nitride layer and to substantially reduce pinholes that would otherwise cause interlevel metal shorts.

    Abstract: A metal interconnection is formed on a dielectric layer. A pre-treatment is then performed to remove organic materials on the surface of the metal layer. The pre-treatment is done by plasma bombardment using NH.sub.3 and NO.sub.2 as the reaction gases. A thin oxide layer is subsequently deposited on the metal layer and on the dielectric layer. The oxide layer serves a buffer layer to eliminate the stress between the metal layer and subsequent silicon nitride layer. A silicon nitride layer is then formed on the thin oxide layer to act as a passivation layer.

    Abstract: A method was achieved for forming a multilayer passivation layer comprised of a silicon oxide/silicon nitride/silicon oxide/silicon nitride by depositing the layers consecutively in a single PECVD system. The method consists of depositing a first SiO.sub.2 layer that serves as a stress-release layer, a thin Si.sub.3 N.sub.4 layer that serves as a buffer layer that minimizes cracking and as a passivation layer that prevents mobile alkaline ion penetration, a thin second SiO.sub.2 layer to fill and seal any remaining cracks and pinholes in the first Si.sub.3 N.sub.4 layer, and a main Si.sub.3 N.sub.4 passivation layer that prevents water and/or other corrosive chemicals from attacking the metal. Since this multilayer passivation layer can be deposited essentially pinhole-free to a thickness that is less than the prior art's passivation layer of 8000 Angstroms needed to prevent pinholes, it can be used on 0.38 to 0.25 um DRAM technology, which eliminates voids that could otherwise trap photoresist which can later cause corrosion of the metal lines.
