PURPOSE: To increase accuracy and contrive the improvement of productivity, by providing a position recognizing mark for semiconductor element electrodes and leads formed on a tape carrier at two points or more in the manufacture of semiconductor devices by a tape carrier system.

CONSTITUTION: In a tape carrier whereon leads 2 are formed, recognizing marks 3 for positioning are provided at two points or more per pattern to accurately position leads when the rotational direction of lead patterns is slid. Thus, a positioning is performed accurate, and a production cost decreases.
