ABSTRACT:
In a tape carrier, one or a plurality of overhang patterns, each being shorter than a length that reaches an edge of a semiconductor chip, is provided in an area where the pitch between adjacent inner leads is relatively large or in a corner area of the device hole where inner leads are not provided, depending upon the size of such area. An average of resin sealing ranges on the rear surface of the tapes is 0.8 mm and the diversification is 0.06 mm.
