polyfuse layout

it's dependent which type fuse types your process owner recommded to you.
two types are all ok.
 

poly fuse layout

If you use a metal fude it is much easier for the fab to "option in/out" resistors. Also for testing the closer to the top layer of metal you use the quicker and cheaper for a new mask and easyier to probe.
Poly is more resistive , ie less space however would be prone to more noise.
