摘要:
A hybrid QFN package includes an encapsulant body that encapsulates a lead frame and integrated circuit (IC) device where the lead frame includes a die pad and vertically offset leads. Back sides of the die pad and encapsulant body are coplanar at first surface. Front sides of the leads, the IC device and the encapsulant body are substantially coplanar at a second surface. An insulating layer covers the second surface except at a portion of the leads located at the peripheral edge of the encapsulating body. Vias extend through the insulating layer to the leads and IC device. Wiring lines on the insulating layer interconnect the vias. A passivation layer covers the wiring lines and vias.

A method (100) for fabricating a semiconductor package comprises providing a die carrier (110), disposing a semiconductor die on the die carrier, the semiconductor die comprising one or more contact pads on a first main face thereof (120), applying an encapsulant at least partially to the semiconductor die, the encapsulant embedding at least one electrical connector, the electrical connector being connected with a contact pad or with the die carrier and extending to a main face of the encapsulant (130), and depositing at least one electrical layer onto the main face of the encapsulant and an exposed end of the at least one electrical connector (140).

A method of dividing a two dimensional array of encapsulated integrated circuits into individual integrated circuit packages uses a first series of parallel cuts (32) extending fully through the leadframe (16) and encapsulation layer (14), and defining rows of the array. The cuts terminate before the beginning and end of the rows such that the integrity of the array is maintained by edge portions (34) at the ends of the rows. After plating contact pads (18), a second series of parallel cuts (36) is made extending fully through the leadframe (16) and encapsulation layer (14). This separates the array into columns thereby providing singulation of packages between the edge portions (34).

An integrated circuit (IC) combines a first IC chip (die) having a first on-chip interconnect structure and a second IC chip having a second on-chip interconnect structure on a reconstructed wafer base. The second IC chip is edge-bonded to the first IC chip with oxide-to-oxide edge bonding. A chip-to-chip interconnect structure electrically couples the first IC chip and the second IC chip.

A compact and high-reliability semiconductor device is implemented. The bonding wires situated in the vicinity of a gate, and the bonding wires situated in the vicinity of a vent facing to the gate across the center of a semiconductor chip in a molding step have a loop shape falling inwardly of the semiconductor chip, have a weaker pulling force (tension) than those of other bonding wires, and are loosely stretched with a margin. The bonding wires situated in the vicinity of the gate in the molding step are, for example, a first wire and a fifth wire to be connected with a first electrode pad and a fifth electrode pad, respectively. Whereas, the bonding wires situated in the vicinity of the vent in the molding step are, for example, a third wire and a seventh wire to be connected with a third electrode pad and a seventh electrode pad, respectively.

A flip chip module having at least one flip chip die is disclosed. The flip chip module includes a carrier having a top surface with a first mold compound residing on the top surface. A first mold compound is disposed on the top surface of the carrier. A first thinned flip chip die resides over a first portion of the first mold compound with interconnects extending through the first portion to the top surface wherein the first portion of the mold compound fills a region between the first flip chip die and the top surface. A second mold compound resides over the substrate and provides a first recess over the first flip chip die wherein the first recess extends to a first die surface of the first flip chip die. A third mold compound resides in the first recess and covers an exposed surface of the flip chip die.
