Abstract
A microelectronic assembly, and method of making the same, including a wire stitch bonded on an electroplated gold bump or electroless nickel/gold bump on a bond pad of an integrated circuit chip. The electroplated gold bump or electroless nickel/gold bump provides a relatively flat upper surface which is excellent for making a wire stitch bond thereto. The microelectronic assembly may include a multiple integrated circuit chip stack attached to a substrate such as a ball grid array. The electroplated gold bumps or electroless nickel/gold bumps may be formed on all of the integrated circuit chips and wire stitch bonds formed on the electroplated gold bumps or electroless nickel/gold bumps thereby connecting the integrated circuit chips to each other or to an underlying ball grid array.
