Abstract

PURPOSE:To make a common TAB tape usable even when the size of chips and position of pads vary more or less by forming inner leads oriented in the same inward direction at nearly equal intervals in such a way that the length of the inner leads becomes longer toward central ones from those at both ends and the inner leads do not cross other inner leads oriented in other directions. CONSTITUTION:A plurality of inner leads 10a oriented in the same direction are formed inward at nearly equal intervals in such a way that the length of the inner leads becomes longer toward central ones from those at both ends and the inner leads do not cross other inner leads oriented in other directions. When this TAB tape is formed in such a way, bonding of the leads to chips having different sizes and shapes can be performed by using this TAB tape.

A plurality of inner leads oriented in the same direction do not intersect with inner leads oriented in other directions, and are formed toward the center so that their lengths increase from the ends to the center while maintaining approximately the same spacing. ing. This allows common use even if the chip size and pad position are slightly different.
