摘要

Spectrosopic ellipsometry has been used to obtain microstructural and layer thickness information from processed SOS wafers consisting of poly-Si/gate oxide/epi-Si/sapphire structures. Oxide thickness and interface roughness increased for 0.1 ¿m SOS wafers. Poly-Si formed by annealing ¿-Si deposited layers had the best dielectric function and similar structure and thicknesses were obtained on bulk and SOS wafers.
