Patent ID: 7705476

Claim:
An integrated circuit package, comprising: a first die, the first die having an active surface and a back surface, the active surface including a plurality of I/O pads, the back surface of the first die having an exposed metallic layer thereon; a leadframe having a plurality of leads, each of the plurality of leads having an inner lead end, an inner lead finger portion, a middle lead portion and an outer lead portion, there being gaps between the inner lead finger portions of the plurality of leads, the outer lead portions of the plurality of leads not being directly physically connected; a first lead of the plurality of leads, the entire first lead following a single linear, non-branching path that is substantially straight and extends directly between the outer lead portion of the first lead and the inner lead end of the first lead, the inner lead finger portion of the first lead electrically coupled via solder joints to a first plurality of the I/O pads, the first plurality of the I/O pads arranged in a substantially straight line, the first lead being electrically connected to the active surface of the die only through the first plurality of the I/O pads, the outer portion of the first lead being exposed on a first side of the package only at a single location on the first side of the package, no portion of the first lead being exposed on a second side of the package opposite the first side; a second lead of the plurality of leads, the entire second lead following a single linear, non-branching path, the second lead extending directly from the outer lead portion of the second lead towards the inner lead end of the first lead, bending around the inner lead end of the first lead and extending alongside and adjacent to the inner lead finger portion of the first lead, the inner lead finger portion of the second lead electrically coupled via solder joints to a second plurality of the I/O pads, the second plurality of the I/O pads arranged in a substantially straight line, the second lead being electrically connected to the active surface of the die only through the second plurality of the I/O pads, the outer lead portion of the second lead being exposed on a second side of the package only at a single location on the second side of the package, no portion of the second lead being exposed on a first side of the package, wherein the inner lead finger portions of the first and second leads are arranged in adjacent rows such that the inner lead finger portion of the first lead extends past the inner lead end of the second lead; and a molding material that encapsulates portions of the first die, leadframe and solder joints while leaving the metallic layer substantially exposed and uncovered by molding material on an outer surface of the package.
