A PHYSICALLY-BASED PREDICTIVE MODEL OF SI SIO2 INTERFACE-TRAP GENERATION RESULTING FROM THE PRESENCE OF HOLES IN THE SIO2/

A physically based model is developed which explains apparently unrela ted aspects of the Si/SiO2 interface trap generation process: the pred ictions of the model are in at least semiquantitative agreement with o bservations previously reported in the literature. The model involves interactions between molecular hydrogen and trivalent silicon dangling bond defects in the oxide (E' centers) and at the Si/SiO2 interface ( P-b centers). Our model is primarily directed at interface trap genera tion caused by ionizing radiation and by hot hole injection phenomena observed in short channel transistors.
