Abstract
A semiconductor device includes a substrate, a metal gate and a poly gate. The substrate includes a first region and a second region. The metal gate is disposed on the first region of the substrate. The poly gate is disposed on the second region of the substrate. A gate area of the poly gate is greater than that of the metal gate.
