PURPOSE:To attach wires accurately to the specific positions of bonding pads, by forming longitudinal and transverse alignment marks in the vicinity of the bonding pads. CONSTITUTION:Alignment marks 5a and 5b which make it possible to determine biaxial positioning are formed in the vicinity of bonding pads 2a and 3a. Then, one of the alignment marks 5b which is formed in the transverse direction is recognized and using its position as an original point, the other one of the alignment marks 5b which is formed in the transverse direction is confirmed. Further, the alignment marks 5a which are formed in the longitudinal direction are recognized and wires are attached to positions where the longitudinal and transverse directional alignment marks 5a and 5b intersect at right angles. Thus, this device may attach the wires accurately to the determined positions of the bonding pads by using the bonding pads as references. |
