An integrated circuit structure is described, and includes a substrate, a contact window, and a Schottky contact metal layer. A heavily doped region and a lightly doped region are formed in the substrate. The contact window is disposed above the heavily doped region, and the Schottky contact metal layer is disposed above the lightly doped region. The Schottky contact metal layer and the substrate form a Schottky diode. The material of the contact window is different from that of the Schottky contact metal layer.
