Abstract
Provided is a semiconductor device including a substrate, an isolation structure, a gate dielectric layer, a high-k dielectric layer, and a protection cap. The substrate includes a first region, a second region, and a transition region located between the first region and the second region. The isolation structure, located in the transition region. The gate dielectric layer is located on the isolation structure. The high-k dielectric layer is located on the isolation structure and extended to cover a sidewall and a surface of the gate dielectric layer. The protection cap is located on a surface and sidewalls of the high-k dielectric layer.
