  • Publication number: 20250056868
    Abstract: A method of fabricating a semiconductor device is provided. Recesses are formed in a substrate. A first gate dielectric material is formed on the substrate and filled in the recesses. The first gate dielectric material on the substrate between the recesses is at least partially removed to form a trench. A second gate dielectric material is formed in the trench. A gate conductive layer is formed on the second gate dielectric material. Spacers are formed on sidewalls of the gate conductive layer. A portion of the first gate dielectric material is removed. The remaining first gate dielectric material and the second gate dielectric layer form a gate dielectric layer. The gate dielectric layer includes a body part and a first hump part at a first edge of the body part. The first hump part is thicker than the body part. Doped regions are formed in the substrate beside the spacers.
