Abstract:
1. An integrated circuit package, comprising: a lead frame including a multiplicity of leads and a die attach pad, the die attach pad having a top surface and a bottom surface, wherein the top surface of the die attach pad has a central region and a recessed region that is lower than the central region; a die including an active surface, a bottom surface substantially opposite the active surface, and a plurality of side surfaces, the active surface having a plurality of I/O pads formed thereon, wherein the die is positioned over the top surface of the die attach pad such that selected edge regions of the bottom surface of the die overhang the recessed region; an adhesive that adhesively bonds the bottom surface of the die to the die attach pad, wherein the adhesive extends along the entire bottom surface of the die and a portion of the adhesive extends into the recessed region and fills the entire portion of the recessed region that directly underlies the bottom surface of the die overhang regions such that a thickness of the adhesive at the overhanging edge regions of the bottom surface of the die is thicker than a thickness of the adhesive at the central region; and a molding material distinct from the adhesive that encapsulates the die and at least portions of lead frame.
