TAB TAPE FOR TAPE CARRIER PACKAGE

摘要

A TAB(Tape Automated Bonding) tape for a TCP(Tape Carrier Package) is provided to prevent the generation of short between adjacent metal lines by distributing the stress converged to a connection portion between first and second leads using a predetermined hole structure. A base film has a chip mounting region for loading a semiconductor chip. A metal line pattern is formed on the base film. The metal line pattern is composed of a plurality of first leads(130), a plurality of second leads(140) and a plurality of connection portions(150) for connecting the first and second leads with each other. A first hole(160) for exposing the base film to the outside is formed on the shortest connection portion and the second lead connected with the shortest connection portion. A second hole is formed at a predetermined portion adjacent to a boundary between the shortest connection portion and the first lead connected with the shortest connection portion.
