Claim:
1. A method of fabricating a tape film package comprising: providing an insulating pattern having a user region and a test region defined by a cutting line; forming a via hole in the insulating pattern of the user region; forming a via contact in the via hole in the insulating pattern; forming first and second interconnection patterns connected to the via contact on an upper surface and a lower surface of the insulating pattern respectively, wherein the first interconnection pattern extends from the user region to the test region, the second interconnection pattern is shorter than the first interconnection pattern in the user region and spaced apart from the cutting line of the insulating pattern; and forming a solder resist on the second interconnection pattern, wherein the second interconnection pattern includes an interconnection region between the insulating pattern and the solder resist, and a pad region exposed by the solder resist from the interconnection region to an end of the second interconnection pattern adjacent the cutting line.
