ABSTRACT:
A fuse structure is described in which a metallic frame is inserted between the insulation layers, through which the fuse window passes, and the final passivation layer. This frame is used as a mask during fuse window formation so alignment is simplified and problems arising from the presence of insulating residues on the surface of the fuse window layer are avoided.
