Abstract :
A simple method of measuring the gate sidewall capacitance (cjg) in MOSFETs is presented. Cjg measurement of a short-channel transistor (Lmin = 40 nm) was successfully achieved by 2-port S-parameter measurement. Furthermore, a merging of source and drain depletion layers and an increase in substrate resistance, both caused by expansion of source and drain depletion layers, were observed through Cjg measurement for the first time.
