CHIP-ON-FILM PACKAGE HAVING BENDING PART
Abstract:
A chip-on-film package comprises a film substrate comprising upper and lower surfaces, and a side having a bending part. A first output interconnection formed on the upper surface of the film substrate extends from a semiconductor chip disposed on the upper surface toward the bending part. A second output interconnection includes an upper output interconnection formed on the upper surface of the film substrate, and a lower output interconnection formed on the lower surface and extending onto the bending part. An input interconnection includes an upper input interconnection formed on the upper surface of the film substrate and a lower input interconnection formed on the lower surface and extending away from the bending part. Through-vias are formed to pass through the film substrate and electrically connect the upper output interconnection to the lower output interconnection, and the upper input interconnection to the lower input interconnection.
