Abstract:
A method for mounting an integrated circuit upon a substrate, said method comprising:fabricating on an integrated circuit a plurality of bonding pads and a non-bonding pad circuit alignment feature patterned using the same mask as that used to form said bonding pads and formed from the same metal layer as said bonding pads; determining the position of the non-bonding pad circuit alignment feature relative to said bonding pads; determining the position of a substrate alignment feature on a mounting surface of the substrate relative to a plurality of contact pads on the mounting surface; and while the plurality of bonding pads faces the plurality of contact pads, establishing a predetermined separation, in a plane parallel to that of the mounting surface, between the non-bonding pad circuit alignment feature and the substrate alignment feature, to effectuate alignment of the plurality of bonding pads to corresponding ones of the plurality of contact pads.
