Low leakage contacts on leakage sensitive areas of a CMOS imager, such as a floating diffusion region or a photodiode, are disclosed. At least one low leakage polysilicon contact is provided over a leakage sensitive area of a CMOS imager. The polysilicon contact comprises a polysilicon region in direct contact with the area of interest (the leakage sensitive area) and a metal region located over the polysilicon region. The polysilicon contact provides an improved ohmic contact with less leakage into the substrate. The polysilicon contact may be provided with other conventional metal contacts, which are employed in areas of the CMOS imager that do not require low leakage.
