Abstract
A semiconductor device and a manufacturing method of the semiconductor device are provided. The semiconductor device includes a substrate, a semiconductor structure, a gate dielectric layer, and a first gate. The semiconductor structure is disposed above the substrate and includes two thick portions and a thin portion located between the two thick portions. A thickness of the two thick portions is larger than a thickness of the thin portion. The gate dielectric layer is disposed on the semiconductor structure. The first gate is disposed on the gate dielectric layer. A width of the first gate is smaller or equal to a width of the thin portion, and the first gate is overlapped with the thin portion in a normal direction of a top surface of the substrate. A doping concentration of the two portions is larger than a doping concentration of the thin portion.
