Abstract

PURPOSE:To clean a semiconductor surface at a low temperature by irradiating it with a light having the same energy as the bond energy of impurity atoms or impurity atoms and semiconductor constituent atoms to dissociate the bond. CONSTITUTION:The surface of a silicon substrate crystal 12 is irradiated with light 11 spectrally separated in coincidence with the energy of a bond to be dissociated from SOR radiated from an electron storage ring. A substrate holder 13 having a heating mechanism can heat a substrate as required. The substrate 12 and the holder 13 are placed in a reaction chamber 14 so designed as to be evacuated in high vacuum by a vacuum evacuator 15. A gas introduction system 16 controls to introduce various gases necessary for an epitaxial growth into the chamber 14. When the surface of the substrate 12 is cleaned, the system is evacuated in high vacuum, and the substrate may be heated. After it is cleaned, epitaxial growth gas, such as silane is fed from the system 16, a substrate temperature is set to a suitable value, and epitaxial growth is performed.
