Abstract:
1. A semiconductor device, comprising: a substrate; a gate insulating layer and a gate formed on the substrate; a source and a drain formed in the substrate and at both sides of the gate; a source sense connected to the source; and a drain sense connected to the drain, wherein the source sense and the drain sense measure an analog channel resistance of the semiconductor device, wherein the analog channel resistance of the semiconductor device is measured by calculating a ratio of a voltage drop between a first and a second voltage difference, and a current difference between a first and a second drain current, wherein the first voltage difference is a voltage difference of the drain sense and the source sense under the condition that currents of the source sense and the drain sense are constrained to zero Ampere, wherein the second voltage difference is a voltage difference of the drain sense and the source sense under the condition that currents of the source sense and the drain sense are constrained to zero Ampere, wherein the first drain current is a current by applying a first voltage to the drain after applying at least one bias voltage of a measuring condition, and wherein the second drain current is a current by applying a second voltage to the drain after applying the at least one bias voltage of the measuring condition.
