METHOD AND DEVICE FOR CUTTING FUSE, FUSE CIRCUIT DEVICE AND CIRCUIT MANUFACTURING METHOD

摘要

PURPOSE: To prevent shorting caused by scattered fragments, even if adjacent fuse electrodes are cut when the plural fuse electrodes continued in the X direction and arranged in the Y direction are cut with a laser beam radiated in the Z direction. CONSTITUTION: When adjacent fuse electrodes 130 are cut it the Y direction, the positions of cutting are made different in the X direction, the adjacent fuse electrodes 130 are cut at remote positions, and shorting is prevented.
