Abstract
A semiconductor device structure is provided. The structure includes a semiconductor substrate and a gate stack over the semiconductor substrate. The structure also includes a sealing element extending along a sidewall of the gate stack. The sealing element has a first atomic layer and a second atomic layer, and the first atomic layer and the second atomic layer have different atomic concentrations of carbon. The structure further includes a spacer element over the sealing element.
