Characterization of thin SOI layers

TL;DRAbstract

Silicon-on-insulator materials still suffer from imperfect electrical and crystalline quality and a spread in performance is observed. Viable characterization techniques are necessary to advance the quality of the materials. This paper gives an overview of characterization methods for silicon-on-insulator materials. Different techniques, both destructive and nondestructive, for determination of silicon and silicon dioxide film thicknesses, structural defects and impurities are reviewed. The potentials and limits of different techniques for silicon-on-insulator material characterization are discussed and some examples of results are given primarily for silicon-on-insulator materials formed by wafer bonding
