ABSTRACT:
A semiconductor device according to the present invention includes a base tape (film carrier tape); a semiconductor chip mounted on the base tape; conducting leads formed on the base tape to be connected to the semiconductor chip; input terminals and output terminals connected to the conducting leads; and a protecting layer formed to cover the conducting leads completely. The base tape is provided at its side edges with roller-contact regions, where carrier rollers are to be in contact with. No holes and no unevenness area is formed on the roller-contact regions.
