Abstract: A field-effect transistor (FET) structure for preventing from shorting is disclosed. The field-effect transistor (FET) structure is applying to a power discrete device, such as the MOSFET or IGBT. The field-effect transistor structure comprises a MOSFET chip and a metal clip. A silver layer (or silver string) is welded on the surface of the metal clip jointed with the source pad so that the silver paste may be not overflowed and permeated into the gate bus to achieve the effect of preventing from shorting.

Abstract: A high heat-dissipation chip package structure for packaging the semiconductor chips is disclosed. A pre-attachment film is adhered on an upper surface of a heat-dissipation plate or a connection plate first and then it is packaged. After packaging, the pre-attachment film is torn off from the upper surface of the heat-dissipation plate or the connection plate. Finally, a metal layer is electroplated on the location of the upper surface of the heat-dissipation plate or the connection plate where the pre-attachment film is torn off so as to improve the fabricating and packaging quality of the semiconductor chips, reduce the cost of cleaning process, and improve the effects of heat dissipation and electrical conductivity.

The MEMS dies are connected to the circuit board by conductive wires and the MEMS dies are separated by the pre mold cavities. A cap is connected to the top of each pre mold cavity to form MEMS die units. The MEMS die units are packed to as to reduce their volume. The manufacturing cost is reduced and the processes are simplified. The MEMS die units are able to be applied to the smaller and fine electronic devices.

Abstract: A molded can package includes a circuit board, a MEMS die and a can. The MEMS die is connected to the circuit board by a conductive wire. The can is mounted to the circuit board so as to isolate the MEMS die to form a MEMS die unit. A compound mold packs the MEMS die unit to prevent the MEMS die from being interfered and physically damage by electro-magnetic radiation and light so as to simplify the manufacturing processes and increase the production and reduce the cost.

Abstract: A chip package includes a conductive connection block connected to the conductive layer coated on the base and the two ends of the gold wire are respectively connected to the chip and the connection block. The connection block prevents lamination during packaging and ensures that the gold wire is firmly connected to the chip and the connection block.

Abstract: A lead frame includes a lead frame 11 made by a rolled single-layer of copper and has a lead portion and a chip support portion. The thickness of the lead portion is the same as that of the chip support portion. A heat dispensing plate made of Aluminum is connected to the chip portion and has a rough surface which is not connected with the lead frame. The lead frame is applied by Laser Diode To Package or metal-Oxide-Semiconductor Field Effect Transistor has high efficiency of heat dispensing and low manufacturing cost, and is suitable for different types of chips.

Abstract: A connection device includes a transistor, a lead frame, a first connection member and a second connection member. The signal is electronically connected between the transistor and the lead frame by the first and second connection members. The second connection member is located above the first connection member so as to increase the communication area for the signals and reduce the resistance between the transistor and the lead frame.

Abstract: The present invention relates to a wire bonding structure, and more particularly to a manufacturing method for said wire bonding structure. The wire bonding structure comprises a die that connects with a lead via a bonding wire. At least one bond pad is positioned on an active surface of the die, and a gold bump is provided on the bond pad; furthermore, a ball bond can be positioned upon the gold bump. The bond pad and the gold bump can separate the ball bond and the die, which can avoid damaging the die during the bonding process.
