Abstract:
A semiconductor device comprising:a semiconductor die having a first plurality of bonding pads disposed along a surface of the die; a lead frame layer comprising a die paddle for supporting the semiconductor die, and a plurality of lead fingers extending from the lead frame layer having a second plurality of bonding pads formed thereon, the die paddle comprising a mounting region, wherein the semiconductor die is mounted adjacent the mounting region of the die paddle so that the die is secured to the die paddle; at least one eyepoint feature that is internally formed as part of the mounting region and extends outwardly from the mounting region of the die paddle so that the eyepoint features and the second bonding pads align with respect to the lead frame layer, wherein the at least one eyepoint feature defines a straight edge and a curved edge that intersect at a point and is visible when the die is being mounted to the mounting region to thereby facilitate registration; and plurality of connecting wires that extend between the first and second bonding pads so as to provide electrically conducting paths therebetween.
