Claims
- 1. A semiconductor device, comprising:
- an integrated circuit chip having an active face with a plurality of bond pads disposed along the center line of the chip;
- a first pair of insulating adhesive tape strips having opposite sides, one side adhered to the active face of the integrated circuit chip, each strip of tape being disposed on an opposite side of the plurality of bond pads;
- a main lead frame having opposite sides and including a plurality of conductive leads adhered to the first pair of the adhesive tape strips on the side opposite the integrated circuit chip;
- a second pair of insulating adhesive tape strips having opposite sides, one side adhered to the main lead frame on the side opposite the first pair of adhesive tape strips;
- bonds for electrically interconnecting the bond pads of the integrated circuit chip with respective leads of the main lead frame at inner ends thereof; and
- a pair of bus lead frames each including a plurality of conductive leads and each adhered to one of the second pair of adhesive tape strips on the side opposite the main lead frame, the leads of each bus lead frame being attached to respective leads of the main lead frame at the outer ends thereof.
- 2. The device of claim 1, wherein the pair of bus lead frames includes a power bus and a ground bus, each bus extending substantially along the length of the integrated circuit chip.
- 3. The device of claim 2, wherein the conductive leads of the main lead frame include:
- a first plurality of leads welded to respective leads of the power bus;
- a second plurality of leads welded to respective leads of the ground bus; and
- a third plurality of leads for connection to external circuitry.
- 4. The device of claim 1, wherein the bonds for electrically interconnecting the bond pads with respective leads of the main lead frame comprise wire bonds.
- 5. The device of claim 1, wherein the bonds for electrically interconnecting the bond pads with respective leads of the main lead frame comprise tab bonds.
- 6. The device of claim 1, wherein the main lead frame and the pair of bus lead frames comprise full hard temper CDA alloy 151.
- 7. The device of claim 6, wherein the integrated circuit chip comprises a dynamic random access memory.
