Abstract
A semiconductor device is provided. The semiconductor device includes a semiconductor substrate, a polysilicon resistive structure, dummy polysilicon resistive structures, and a polysilicon ring structure. The semiconductor substrate has an active region and a passive region adjacent to the active region. The polysilicon resistive structure is disposed on an isolation structure in the passive region. The dummy polysilicon resistive structures are disposed on the isolation structure, respectively disposed outside opposite sides of the polysilicon resistive structure. The polysilicon ring structure is disposed on the isolation structure, encircling the polysilicon resistive structure and the dummy polysilicon resistive structures.
