Abstract
The present disclosure provides a semiconductor device. The semiconductor device includes a substrate, having a plurality of fins on a surface of the substrate; a gate structure across the plurality of fins. The gate structure is located on a portion of a top surface and sidewall surfaces of the plurality of fins. The gate structure includes a first region and a second region on the first region. A bottom boundary of the second region is higher than the top surface of the plurality of fins. A size of the first region in an extending direction of the plurality of fins is smaller than a size of the second region in the extending direction of the plurality of fins.
