Abstract

A semiconductor device structure is provided. The semiconductor device structure includes a substrate. The semiconductor device structure includes a first fin structure and a second fin structure over the substrate. There is a gap between the first fin structure and the second fin structure. The semiconductor device structure includes an isolation structure having a thin portion and a thick portion. A first upper portion of the first fin structure and a second upper portion of the second fin structure protrude from the thin portion. The thick portion is partially between the first upper portion and the second upper portion. The semiconductor device structure includes a dummy gate electrode over the thick portion, the first upper portion, and the second upper portion. The semiconductor device structure includes a gate electrode over the first fin structure and the thin portion.
