We investigated the process of Pb center generation during silicon oxidation following oxygen termination on a clean Si surface, based on which we discuss the microscopic origin of Pb centers. We constructed a UHV-ESR system which enabled measurements to be carried out at a low temperature of around 100 – 120 K, and used the system to study the Si(111)-7×7 surface after slight exposure to O2. Based on the observed ESR spectra, we discuss the electronic structure of the Si(111)-7×7 surface.
