Se. Leang et al., A NEW GATE CURRENT MEASUREMENT TECHNIQUE FOR THE CHARACTERIZATION OF HOT-CARRIER-INDUCED DEGRADATION IN MOSFETS, Solid-state electronics, 38(10), 1995, pp. 1791-1798
A new gate current measurement method is proposed for the characteriza
tion of hot-carrier induced degradation in MOSFETs. This method requir
es a much shorter measurement time to obtain the I-g-V-g curve of the
MOSFETs as compared to the conventional floating-gate technique, and t
herefore has a lower risk of degrading the test device during the meas
urement process. This paper also discusses the appropriateness of usin
g a high-frequency (100 kHz-1 MHz) measurement to obtain the gate capa
citance of MOSFETs when applying the floating-gate technique to obtain
the device gate current.
