Abstract:
1. A method for manufacturing a semiconductor package comprising: printing a first adhesive material onto a plurality of front electrodes 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; applying a second high temperature for connecting the plurality of front electrodes of a semiconductor chip onto a plurality of metal connection plates by flipping the semiconductor chip and adhering the pre-cured first adhesive material on each front electrode to one of the plurality of the metal connecting plates; printing a second adhesive material on a plurality of adhesive zones on a chip carrier of a lead frame at room temperature followed by curing the adhesive material at a third high temperature; applying a fourth high temperature for connecting the chip carrier to a bottom of the semiconductor chip by adhering the pre-cured second adhesive material to the bottom of the semiconductor chip; and applying a molding material to encapsulate the semiconductor chip and at least portions of the lead frame and the metal connections plates.
