Properties of Si/buried oxide (BOX) systems with bonded interface in silicon-on-insulator (SOI) wafers were studied in this paper. Results show impact of the starting Si material - Czochralski (Cz) or float-zone (Fz) grown silicon on the electron mobility (μe) and BOX charge behavior in ultrathin SOI layers. In particular, there were found: 1) the μe ~ Ne-0.3 dependencies at the electron density Ne in the range of 4х (1011-1012) cm-2 in accumulation Cz-SOI layers with the μe degradation when Si thickness decreases from 20 to 9 nm, and 2) the ~ Ne-0.6 behavior of mobility with no degradation in Fz-SOI layers. Raman spectroscopy shows the structural modification of Cz-SOI layers. An origin of degradation of the electrical and structural properties for ultrathin SOI layer is discussed.
