Abstract
In a COF manufactured by bonding and mounting a semiconductor element onto a wiring pattern on a lengthy tape carrier, the wiring patterns are aligned in more than one direction with respect to a direction in which the tape carrier is fed. The wiring patterns have a layout that increases a utilized area of the tape carrier (in other words, such that reduces useless areas). Consequently, the number of the tape carrier semiconductor devices manufactured out of a tape carrier of a certain length can be increased thereby saving manufacturing costs.
