Patent ID: 8198727

Claim:
An apparatus, comprising: an integrated circuit including a plurality of bond pads; a substrate including a plurality of landing pads and a mask that is spaced from the landing pads for defining areas therebetween; and a plurality of interconnects connected between the bond pads of the integrated circuit and the landing pads of the substrate, the interconnects including a plurality of metal projections extending from the bond pads of the integrated circuit, each of the metal projections having a diameter greater than a lateral width of each of the landing pads, and a solder material for connecting the metal projections and the landing pads of the substrate; wherein the solder material fills the areas; wherein a bump pitch is reduced as a result of the solder material filling the areas; wherein the landing pads are coplanar with respect to the mask; wherein a polymide layer is deposited between the integrated circuit and the substrate, and the polymide layer deposited between the integrated circuit and the substrate extends to 75% of a height of each of the metal projections.
