Abstract: A chip carrier for carrying a chip including a carrier and at least one signal collection tape is provided. The carrier has a surface, a die pad and a plurality of inner leads surrounding the die pad, and the signal collection tape is disposed on the surface of the carrier, and is electrically connected to the chip. The signal collection tape is used to replace the conventional power ring and ground ring and to decrease the length of bonding wire, thus reducing the package size.

Abstract: A leadframe includes a die pad, a plurality of tie bars, a plurality of metal extrusions and a plurality of leads. The leads are arranged around the die pad. The tie bars are connected to the corners of the die pad, and the metal extrusions are connected to the sides of the die pad but separated from the tie bars. Each metal extrusion has a locking hole and a bonding surface, which is higher than the die pad. The metal extrusions are configured for improving ground connections by wire-bonding. When a bottom surface of the die pad is exposed from an encapsulant for a semiconductor package, the metal extrusions help to secure the die pad without stress transmission.

Abstract: In a leadframe packaging structure, a leadframe includes a plurality of first leads, a plurality of second leads, and a die pad. The first leads define a chip-bonding region in which is arranged the die pad. The second leads extend and terminate into a plurality of contact pads in the chip-bonding region. An adhesive tape further is bonded on bottom surfaces of the contact pads. A chip is bonded on the die pad. At least a passive device is mounted between and electrically connects the contact pads. A plurality of bonding wires respectively connect the chip, the passive device, and the first and second leads. An encapsulant material encapsulates the chip, the passive device, and the bonding wires.
