The experiments concerning the oxidation of Si(001) were performed at the surface reaction analysis apparatus, installed at the beamline BL23SU in the SPring-8. The SiO desorb remarkably at surface temperature of 1000 K. The desorption yield increased with increasing the incident energy of O. On the other hand, the desorption yield increased with decreasing the incident energy in the temperature region lower than 1000 K. Oxygen uptake curves observed by O-1s photoemission measurements corresponded to the SiO desorption features. These facts reveal that the passive oxidation coexists with the SiO desorption in the temperature region from 900 K to 1000 K.
