Abstract:
A method for forming a semiconductor device, comprising:providing a semiconductor wafer having an active surface, said active surface having bond pads thereon; forming conductive traces over said active surface, each of said conductive traces having a first end, a second end, a top surface, and a bottom surface, said bottom surface of said first end of each said conductive trace being in contact with at least one of said bond pads; forming a conductive bump on said top surface at said second end of said conductive traces, said conductive bump having a top portion transverse to said top surface of said conductive traces; planarizing said top portion of said conductive bump; forming a layer of encapsulation material to cover said active surface of said semiconductor wafer and to surround said conductive bump; and reforming said conductive bump to a preplanarized shape extending above said layer.
