Abstract
The present disclosure relates to a method of fabricating a semiconductor device. A semiconductor device includes a bond pad and a fuse layer. The bond pad includes a coating on an upper surface. A dielectric layer is formed over the bond pad and the fuse layer. A passivation layer is formed over the dielectric layer. An etch is performed to form a bond pad opening and a fuse opening. The etch is performed using only a single mask. The fuse opening defines a fuse window. The upper surface of the bond pad is exposed by substantially removing the coating from the entire upper surface.
