ABSTRACT:
Electrically programmable fuse structures and methods of fabrication thereof are presented, wherein a fuse includes first and second terminal portions interconnected by an elongate fuse element. The first terminal portion has a maximum width greater than a maximum width of the fuse element, and the fuse includes a narrowed width region where the first terminal portion and fuse element interface. The narrowed width region extends at least partially into and includes part of the first terminal portion. The width of the first terminal portion in the narrowed region is less than the maximum width of the first terminal portion to enhance current crowding therein. In another implementation, the fuse element includes a restricted width region wherein width of the fuse element is less than the maximum width thereof to enhance current crowding therein, and length of the restricted width region is less than a total length of the fuse element.
