摘要: A method of removing carbon contamination. On a semiconductor substrate having carbon contamination thereon, a sacrificial oxide layer is formed. During the formation of the sacrificial oxide layer, an agent is introduced to help and improve the growth of the sacrificial oxide layer, and to trap the carbon contamination. The sacrificial oxide layer is then removed, and the carbon contamination is removed with the sacrificial oxide layer.
