    Abstract: A method for testing the threshold stability of a MOSFET device including a phosphosilicate glass (PSG) thin film which covers the gate insulator to trap contaminants. The test comprises an electric field stress at ambient temperature for a short interval to determine polarization of the PSG film. The flat band potentials (VFB) measured before and after the stress period are used to determine whether the amount of PSG is sufficient to trap the contaminants present.
