    • PURPOSE: A method for forming a fuse is provided to enhance efficiency of a fabrication process by omitting a process for removing a fence. CONSTITUTION: A metal barrier and a metal layer are sequentially on a substrate(30).

Thereafter, the anti-reflective layer(25) is removed, and the second polysilicon layer is formed overall. The second polysilicon layer is then removed but remaining a spacer on a sidewall of the first polysilicon layer(24). After that, the buffer layer(32) is removed, and the minute pattern of the floating gate is obtained.
