摘要： A HV MOSFET device includes a substrate, a deep well region, a source/body region, a drain region, a gate structure, and a first doped region. The deep well region includes a boundary site and a middle site. The source/body region is formed in the deep well region and defines a channel region. The first doped region is formed in the deep well region and disposed under the gate structure, and having the first conductivity type. There is a first ratio between a dopant dose of the first doped region and a dopant dose of the boundary site of the deep well region. There is a second ratio between a dopant dose of the first doped region and a dopant dose of the middle site of the deep well region. A percentage difference between the first ratio and the second ratio is smaller than or equal to 5%.
