Abstract: Embodiments of mechanisms for forming a semiconductor device are provided. The semiconductor device includes a semiconductor substrate. The semiconductor device also includes an isolation structure in the semiconductor substrate and surrounding an active region of the semiconductor substrate. The semiconductor device includes a gate over the semiconductor substrate. The gate has an intermediate portion over the active region and two end portions connected to the intermediate portion. Each of the end portions has a first gate length longer than a second gate length of the intermediate portion and is located over the isolation structure.
