Abstract
An integrated circuit device is provided. The integrated circuit device includes a semiconductor substrate having a circuit area and a guarding area surrounding the circuit area. A guarding structure is formed in the guarding area, and includes a diffusion region in the semiconductor substrate. The guarding structure also includes a gate stack disposed on the semiconductor substrate and positioned adjacent to the diffusion region. The guarding structure further includes a guarding layer disposed on the gate stack. The gate stack extends in a first direction while the guarding layer extends in a second direction that is different from the first direction. The guarding layer is electrically insulated from the diffusion region. Thus, an integrated circuit device including a guarding structure with several capacitors is provided.
