A conductive cap having a predetermined thickness is formed over the metal bonding pad. A bonding element is bonded to the conductive cap to form an electrical connection with the metal bonding pad.

Abstract: A new method of fabricating self-aligned, anti-via interconnects has been achieved. A semiconductor substrate is provided. A metal layer is deposited overlying the semiconductor substrate. The metal layer may comprise a composite stack of two metal layers. The metal layers may additionally be separated by an etch stopping layer. An anti-reflective coating layer is deposited overlying the metal layer. The metal layer is etched through to form connective lines. The metal layer is then etched partially through to form vias. The partial etching through may be accomplished by timed etching or by use of the optional etching stop layer. A dielectric layer is deposited overlying the vias, the connective lines and the semiconductor substrate. The dielectric layer may comprise a low-k material. The dielectric layer is polished down to complete the self-aligned, anti-via interconnects in the manufacture of the integrated circuit device.

Abstract: A new method to prevent copper contamination of the intermetal dielectric layer during via or dual damascene etching by forming a capping layer over the first copper metallization is described. A first copper metallization is formed in a dielectric layer overlying a semiconductor substrate wherein a barrier metal layer is formed underlying the first copper metallization and overlying the dielectric layer. The first copper metallization is planarized, then etched to form a recess below the surface of the dielectric layer. A conductive capping layer is deposited overlying the first copper metallization within the recess and overlying the dielectric layer. The conductive capping layer is removed except over the first copper metallization within the recess using one of several methods. An intermetal dielectric layer is deposited overlying the dielectric layer and the conductive capping layer overlying the first copper metallization.
