Abstract:
1. A tape wiring substrate for use in a chip-on-film (COF) package, the substrate comprising: a base film configured to receive a semiconductor chip thereon; an input/output (I/O) wiring pattern for transmitting I/O signals to and from the semiconductor chip through an electrode bump disposed on the semiconductor chip when the semiconductor chip is mounted on the base film, the I/O wiring pattern disposed on the base film and configured to receive the electrode bump; a dispersion wiring pattern disposed on the base film, the dispersion wiring pattern configured to receive a dispersion bump that is immediately adjacent to the electrode bump; and a connecting wiring pattern disposed on the base film, the connecting wiring pattern connecting an end of the dispersion wiring pattern to the I/O wiring pattern.
