Abstract
A semiconductor device is provided. The semiconductor device includes a semiconductor substrate. The semiconductor device includes an isolation structure in the semiconductor substrate. The isolation structure surrounds an active region of the semiconductor substrate. The semiconductor device includes a gate over the semiconductor substrate. The gate is across the active region and extends onto the isolation structure. The semiconductor device includes a support film over the isolation structure. The support film is a continuous film which continuously covers the isolation structure and the gate over the isolation structure.
