Abstract:
1. A method for manufacturing a semiconductor package comprising: pre-printing a first adhesive material onto a plurality of front electrodes and a back electrode of a semiconductor chip disposed on a wafer at room temperature followed by pre-curing the adhesive material at a first temperature then dicing the wafer into a plurality of semiconductor chips; pre-printing a second adhesive material on a plurality of adhesive zones including a chip carrier and pins on a lead frame at room temperature followed by curing the adhesive material at a second high temperature; applying a third high temperature for adhering the back electrode of the semiconductor chip to the chip carrier of the lead frame; providing metal connector plates and applying a fourth high temperature for adhering the metal connector plates to the front electrodes and the pins on the leadframe; and applying a molding material to encapsulate the semiconductor chip and at least portions of the lead frame and the metal connections plates.
