Claim 7:
8. The method for evaluating the HCI effect of the device of claim 1, wherein determining the influence of the process parameter adjustment or the device parameter adjustment on the HCI effect of the device based on the second current ratio and the first current ratio comprises:
acquiring a curve showing a change of the first current ratio over the gate-source voltage of the first device;
acquiring a curve showing a change of the second current ratio over the gate-source voltage of the second device; and
determining the influence of the process parameter adjustment or the device parameter adjustment on the HCI effect of the device based on the curve showing the change of the first current ratio over the gate-source voltage and the curve showing the change of the second current ratio over the gate-source voltage.
