Patent ID: 7411289

Claim:
An integrated circuit package comprising: a semiconductor die mounted to a die attach pad; a plurality of contact pads circumscribing said die attach pad; each of said contact pads having, a central portion, an interior peripheral portion, located on an interior side of the central portion between the central portion and the die attach pad, and proximate to a first side of the central portion, and an exterior peripheral portion, located on an exterior side of the central portion, opposite the interior peripheral portion, and proximate a second side of the central portion, wherein the interior peripheral portion and the exterior peripheral portion have respective thicknesses less than a thickness of the central portion; wire bonds connecting said semiconductor die to at least one of said contact pads; an overmold covering a first side of said semiconductor die, said wire bonds, said internal peripheral portion of each of said contact pads, and a portion of the first side of said contact pads such that a remaining portion of said first side of said contact pads is uncovered and the second side of said contact pads is uncovered; external contacts disposed on said first side of said contact pads, at the uncovered remaining portion, the external contacts forming balls which protrude from said overmold; and at least one of an active and a passive component mounted to said second side of at least one of, said die attach pad and at least one of said contact pads, wherein a maximum thickness of the central portion of each of the plurality of contact pads is substantially equal to a combined thickness of the die attach pad and the semiconductor die.
