Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 8:
9. The method for evaluating the HCI effect of the device of claim 8, wherein the method for 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 comprises: under a same gate-source voltage, when the second current ratio is higher than the first current ratio, determining that the process parameter adjustment or the device parameter adjustment enhances the HCI effect of the device; and when the second current ratio is lower than the first current ratio, determining that the process parameter adjustment or the device parameter adjustment reduces the HCI effect of the device.
