Abstract
Charge pumping is one of the most relied upon techniques used to quantify interface defects in metal-oxide-semiconductor devices. However, conventional charge pumping is easily hindered by excessive gate leakage currents which render the technique unsuitable for advanced technology nodes. We demonstrate a new frequency-modulated charge pumping methodology in which we transform the quasi-DC charge pumping measurement into an AC measurement. The AC detection scheme is highly resistant to gate leakage currents and extends the usefulness of charge pumping as a defect monitoring tool for future technologies.Citation
