1. A method of packaging a semiconductor die, comprising:
mounting the semiconductor die on a carrier;
electrically connecting electrical contact pads of the semiconductor die to external electrical contacts;
encapsulating the semiconductor die with a mold compound to form a packaged die; and
thinning the mold compound on a top, non-active side of the packaged die using a saw blade,
wherein the carrier comprises a lead frame and the semiconductor die is mounted on a die pad of the lead frame and attached thereto with a die attach material, the external electrical contacts comprise lead fingers of the lead frame, and the die electrical contact pads are electrically connected to the lead fingers with bond wires.
