A time-dependent technique for carrier recombination and generation lifetime measurement in SOI MOSFET

A time-dependent technique is developed for carrier recombination-generation (R-G) lifetimes measurement in the silicon-on-insulator (SOI) metal-oxide-semiconductor field-effect transistor (MOSFET). One gate is kept in strong accumulation, and the other gate is kept in strong inversion. A ramp voltage is applied to the accumulated gate, and the drain current transients are monitored for both carrier R-G lifetimes extraction. The time-dependent technique shows an extensive applicability, and its credibility is proved by simulation.
