Patent ID: 7122124

Claim:
A method of fabricating a film carrier, comprising the steps of: providing a film; forming a metallic layer over the film; forming a first photoresist layer over the metallic layer and a second photoresist layer over the film on a side away from the metallic layer, wherein the first photoresist layer has a plurality of first openings and the second photoresist layer has a plurality of second openings; removing a portion of the metallic layer to form a plurality of metallic leads using the first photoresist layer as an etching mask; forming a third photoresist layer over the metallic leads and the first photoresist layer; removing a portion of the film to form a plurality of openings using the second photoresist layer as an etching mask and the third photoresist layer as an etch stop; and removing the first photoresist layer, the second photoresist layer and the third photoresist layer.
