Closely pitched polysilicon fuses and method of forming the same |
摘要 |
A method for decreasing the pitch of polysilicon fuses uses tungsten barriers formed adjacent to the fuse elements. The tungsten barriers are made compatible with the process to form a crack stop by stacking tugsten at the via level on top of the tungsten at the contact level in the crack stop. An interlevel dielectric is used as a cover for the fuse.
