Comparative materials characterization of SOI wafers produced by competing technologies

Abstract

In this work we have used established and novel analysis techniques to compare SOI wafers produced by wafer-bonding and different thinning techniques such as chemical-mechanical thinning, plasma etching and wet etching, and by separation-by-implanted-oxygen (SIMOX). The techniques employed were optical-beam-induced reflectance, positron annihilation, atomic force microscopy and X-ray diffractometry.<>
