Abstract
A ceramic or plastic body has a shelf comprising conductive traces. A semiconductor die is attached to the underside of the shelf, or to a base of the body. A void or voids in said shelf allows the passage of bond wires to couple the bond pads of the inferiorly positioned semiconductor die with said conductive traces. Manufacturable from ceramic, plastic, or any workable material, various described embodiments of the invention alleviate the need for a lead frame while being usable with a die having bond pads located either centrally or laterally. The invention can receive die of various dimensions without a change of design while allowing short bond wire lengths for each die size.
Claims20
A body for receiving a semiconductor die, said body comprising:
- a) a first shelf for receiving a lid;
- b) a second shelf having conductive traces thereon, said second shelf overlying a portion of the semiconductor die, wherein said traces couple with bond pads on the semiconductor die;
- c) a third shelf for receiving a base;
- and
- d) conductive leads for electrically coupling with an electronic device, wherein said conductive leads electrically couple with said conductive traces.
A logic component comprising:
- a) a semiconductor die;
- b) a body for receiving said semiconductor die;
- c) a lid and a base receivable by said body;
- d) a first shelf for receiving said lid;
- e) a second shelf having conductive traces thereon, said second shelf overlying a portion of the semiconductor die, wherein said traces couple with bond pads on the semiconductor die;
- f) a third shelf for receiving said base;
- and
- g) conductive leads for electrically coupling with an electronic device, wherein said conductive leads electrically couple with said conductive traces.
