    摘要: A gate stack structure with an etch stop layer is provided. The gate stack structure is formed over a substrate. A spacer is formed on a sidewall of the gate stack structure. The gate stack structure includes a gate dielectric layer, a barrier layer, a repair layer and the etch stop layer. The gate dielectric layer is formed on the substrate. The barrier layer is formed on the gate dielectric layer. The barrier layer and an inner sidewall of the spacer collectively define a trench. The repair layer is formed on the barrier layer and an inner wall of the trench. The etch stop layer is formed on the repair layer.

    摘要: A method of fabricating a semiconductor device includes following steps. A substrate is provided, wherein a first dielectric layer having a trench therein is formed on the substrate, a source/drain region is formed in the substrate at two sides of the trench, and a second dielectric layer is formed on the substrate in the trench. A first physical vapor deposition process is performed to form a Ti-containing metal layer in the trench. A second physical vapor deposition process is performed to form an Al layer on the Ti-containing metal layer in the trench. A thermal process is performed to anneal the Ti-containing metal layer and the Al layer so as to form a work function metal layer. A metal layer is formed to fill the trench.
