Abstract
The dynamic events which occur at the silicon/oxide interface during oxidation are of fundamental importance both in developing models to explain oxidation kinetics and in understanding how interface structure influences the properties of microelectronic devices. Of particular interest is the evolution of interface roughness during oxidation. With modern gate oxides only a few atomic layers thick, any roughness at the silicon/oxide interface affects device performance significantly so that understanding and controlling interface morphology becomes necessary. Interface step behaviour is also important in understanding the mechanism of the oxidation reaction, helping to develop models for the reactivity of atoms at different sites and the order in which bonds are broken. Furthermore, the flow of surface steps during active oxidation (also referred to as etching) can be a powerful tool to modify surface morphology, as required in some interesting novel devices. So from both a practical and a fundamental point of view there is great interest in following the structural evolution of the silicon/oxide interface during oxidation.
