Abstract
High-speed measurement of field-effect transistor (FET) threshold voltage at low drain current has been achieved by using an analog feedback method with proper guarding techniques. The method can be applied to process control test structure FETs and/or to characterize FETs which may be formed in high-density metal-oxide semiconductor large-scale integration circuits. Ease of operation has been augmented by dedicated software. With correct application of the guard technique, it is proved that Vth at low Id such as 1 nA can be measured in a reasonable measurement time.
