Abstract
A semiconductor device includes: an e-fuse gate, a floating pattern between the e-fuse gate and an e-fuse active portion, a blocking dielectric pattern between the floating pattern and the e-fuse gate, and an e-fuse dielectric layer between the floating pattern and the e-fuse active portion. The floating pattern includes a first portion between the e-fuse gate and the e-fuse active portion and a pair of second portions extended upward along both sidewalls of the e-fuse gate from both edges of the first portion.
