Abstract

A method for fabricating an integrated circuit chip includes the steps of: PA1 (a) forming a circuit board unit with a die-receiving cavity, and a plurality of contact pads on a top surface of the circuit board unit; PA1 (b) forming a die having an upper surface provided with a plurality of solder pads; PA1 (c) placing the die in the die-receiving cavity such that the solder pads on the die are exposed; PA1 (d) wire-bonding the solder pads to the contact pads via conductive wires; PA1 (e) placing a lead frame on the circuit board unit, and connecting leads on the lead frame to corresponding ones of the contact pads via a conductive contact layer; and PA1 (f) forming a plastic protective layer to encapsulate the circuit board unit and at least a portion of the lead frame.
