Abstract
An electronic fuse link with lower programming current for high performance and self-aligned methods of forming the same. The invention provides a horizontal e-fuse structure in the middle of the line. A reduced fuse link width is achieved by spacers on sides of pair of dummy or active gates, to create sub-lithographic dimension between gates with spacers to confine a fuse link. A reduced height in the third dimension on the fuse link achieved by etching the link, thereby creating a fuse link having a sub-lithographic size in all dimensions. The fuse link is formed over an isolation region to enhanced heating and aid fuse blow.
