摘要： A semiconductor device comprises an aluminum alloy lead-frame with a passivation layer covering an exposed portion of the aluminum alloy lead-frame. Since aluminum alloy is a low-cost material, and its hardness and flexibility are suitable for deformation process, such as punching, bending, molding and the like, aluminum alloy lead frame is suitable for mass production; furthermore, since its weight is much lower than copper or iron-nickel material, aluminum alloy lead frame is very convenient for the production of semiconductor devices.

摘要： The invention relates to a semiconductor package of a flip chip and a method for making the semiconductor package. The semiconductor chip comprises a metal-oxide-semiconductor field effect transistor. On a die paddle including a first base, a second base and a third base, half-etching or punching is performed on the top surfaces of the first base and the second base to obtain plurality of grooves that divide the top surface of the first base into a plurality of areas comprising multiple first connecting areas, and divide the top surface of the second base into a plurality of areas comprising at least a second connecting area. The semiconductor chip is connected to the die paddle at the first connecting areas and the second connecting area.
