摘要：

F2 plasma-Si(100) surface interaction experiments have been conducted to understand basic mechanisms of surface modifications. Surface analysis has been investigated using x-ray photoelectron spectroscopy and nuclear reaction analysis. The experiments show deep penetration of fluorine into silicon and limitation of etching caused by oxide layers coming from contamination of the plasma by removal of oxygen from alumina walls of the reactor. Biasing of the silicon substrate enhanced carbon contamination.
