Abstract:
A method of making a chip-exposed semiconductor package comprising the steps of: plating a plurality of electrode on a front face of each chip on a wafer; grinding a backside of the wafer and depositing a back metal then separating each chips; mounting the chips with the plating electrodes adhering onto a front face of a plurality of paddle of a leadframe; adhering a tape on the back metal and encapsulating with a molding compound; removing the tape and sawing through the leadframe and the molding compound to form a plurality of packaged semiconductor devices.
