Abstract
Surface charge spectroscopy (SCS) is investigated by X-ray photoelectr on spectroscopy (XPS) and the results are compared with C(V) and G(V) low frequency density of states data obtained on MOS capacitors, perfo rmed using a SILO/RTN (sealed interface local oxidation of silicon/rap id thermal nitridation) based isolation process. The surface density o f states is found to be correlated to initial oxygen content at variou s nitridation temperatures. Good agreement is obtained between both me thods and metallic contamination measurements by secondary ion mass sp ectroscopy (SIMS) for surface state density as low as 10(11) to 10(12) cm-2 eV-1.
