Abstract
A triple operation voltage device including a first type substrate, a high voltage (HV) first type well, a second type well, a low voltage (LV) device well, and a middle voltage (MV) device well is provided. The HV first type well is disposed inside the first type substrate. The second type well is disposed inside the first type substrate to separate the HV first type well from the first type substrate. The LV device well and the MV device well are separately disposed inside the HV first type well by the separation of the HV first type well. The triple operation voltage device assists in reducing the space between the LV device well and the MV device well and improving the integration of integrated circuits.
