Abstract

The influence of oxide patterned layers on the thickness of SiO2 films (30 to 70 A) grown on polycrystalline silicon by rapid thermal oxidation (RTO) is reported. Oxide thicknesses are examined using C- V and XTEM analysis. The measurements reveal significant oxide thickness increases (up to 50%) due to the presence of the oxide patterns, and the local temperature increases resulting from the surface patterns are estimated. The reasons for this effict are discussed, as are the device-level implications and the potential opportunities to exploit these findings.
