Abstract
A semiconductor device structure is provided. The semiconductor device structure includes a semiconductor substrate. The semiconductor device structure includes a gate stack positioned over the semiconductor substrate. The gate stack includes a gate dielectric layer and a gate electrode over the gate dielectric layer. The semiconductor device structure includes spacers positioned over first sidewalls of the gate stack. The spacers and the gate stack surround a recess. The semiconductor device structure includes an insulating layer formed over the semiconductor substrate and surrounding the gate stack. The semiconductor device structure includes a cap layer covering the insulating layer, the spacers, and inner walls of the recess.
