Patent ID: 7619303

Claim:
An integrated circuit package, comprising: a first die, the first die having an active surface and a back surface substantially opposite the active surface of the first die, the active surface including a first plurality of I/O pads; a second die, the second die having an active surface and a back surface substantially opposite the active surface of the second die, the active surface including a second plurality of I/O pads; a plurality of leads that are physically separate from one another, each lead having a first surface and a second surface substantially opposite the first surface of the lead, the active surface of the first die being positioned adjacent first surfaces of leads such that I/O pads from the first plurality of I/O pads are arranged adjacent corresponding solder pad surfaces on the first surfaces of the leads, the active surface of the second die being positioned adjacent second surfaces of leads such that I/O pads from the second plurality of I/O pads are arranged adjacent corresponding solder pad surfaces on the second surfaces of the leads, the first surface of each lead including a first plurality of solder pad surfaces and a corresponding first plurality of recessed regions that isolate each of the first plurality of solder pad surfaces from other surfaces of the lead, the second surface of each lead including a second plurality of solder pad surfaces and corresponding second plurality of recessed regions that isolate each of the second plurality of solder pad surfaces from other surfaces of the lead; a first plurality of solder joints that are arranged to physically and electrically connect selected ones of the I/O pads from the first die to ones of the first plurality of solder pad surfaces on the first surface of each lead; and a second plurality of solder joints that are arranged to physically and electrically connect selected ones of the I/O pads from the second die to ones of the second plurality of solder pad surfaces on the second surface of each lead, wherein each of the first plurality of recessed regions on the first surface of each lead are offset from each of the second plurality of recessed regions on the second surface of the lead in a direction parallel to the first and second surfaces of the lead.
