Abstract
Embodiments provide an electronic device. The electronic device includes a leadframe having a first face that defines an island and multiple leads configured to communicate with a chip attached to the island, a first structure element separate from and coupled to a first face of the leadframe, at least one electrical connector coupled between the chip and the first structure element, and at least one electrical connector coupled between the first structure element and one of the multiple leads.
Claims25
An electronic device comprising:
- a leadframe comprising a first face that defines an island and multiple leads configured to communicate with a chip attached to the island;
- a first structure element separate from and coupled to the first face of the leadframe;
- at least one electrical connector coupled between the chip and the first structure element;
- and
- at least one electrical connector coupled between the first structure element and one of the multiple leads.
A semiconductor device including at least one chip, the semiconductor device comprising:
- a leadframe comprising a die pad and adjacent tiebars extending from the die pad;
- and
- at least one bus coupled to and electrically isolated from the adjacent tiebars of the leadframe and electrically isolated from the die pad.
A semiconductor assembly comprising:
- a printed circuit board;
- and
- a semiconductor package electrically coupled to the printed circuit board, the semiconductor package comprising:
- a leadframe comprising a die pad, tiebars extending from the die pad, and multiple leads configured to electrically communicate with the die pad,
- a chip attached to the die pad,
- a first structure element separate from the leadframe and coupled to the tiebars, the first structure element separated from each of the multiple leads;
- a first connector electrically coupling the chip and the first structure element,
- a second connector electrically coupling the first structure element to one of the multiple leads.
A method of fabricating a semiconductor package comprising:
- providing a leadframe strip comprising at least one leadframe, each leadframe including an island and multiple leads;
- attaching a structure element to the at least one leadframe;
- attaching a chip to the island of the at least one leadframe;
- electrically connecting the chip to the structure element;
- and
- electrically connecting the structure element to one of the multiple leads.
A semiconductor device comprising:
- a leadframe comprising a die pad, a pair of spaced tiebars extending from the die pad, and multiple leads configured to electrically communicate with a chip coupled to the die pad;
- a first bus coupled between the spaced tiebars;
- at least one additional bus coupled between the spaced tiebars;
- wherein the first bus is coupled to a first set of the multiple leads to define one of a ground bus and a power bus and the at least one additional bus is coupled to a second set of the multiple leads to define one of a ground bus and a power bus.
