A semiconductor structure having an efficient thermal path and a method
for forming the same are provided. The semiconductor structure includes a
protection ring over a semiconductor substrate and substantially encloses
a laser fuse structure. The laser fuse structure includes a laser fuse
and a connection structure connecting the fuse to integrated circuits.
The protection ring is thermally coupled to the semiconductor substrate
by contacts. The semiconductor structure further includes a metal plate
conducting heat generated by a laser beam to the protection ring.
