Abstract
In one embodiment the present invention includes a method of fabricating a chip scale package (CSP). The method includes forming conductive bumps on a top side of a semiconductor wafer; mounting the top side of the semiconductor wafer on adhesive tape; sawing the semiconductor wafer a first time such that a wide sawing kerf is obtained; molding the semiconductor wafer with a molding compound; and sawing the semiconductor wafer a second time to obtain the CSPs. Such method has improved efficiency as compared to many existing methods of fabricating CSPs.
