The epitaxial growth of Si films on CaF//2/Si heteroepitaxial structures and characteristics of MOSFET's fabricated in the Si/CaF//2/Si structures are investigated. Both the growth of the Si/CaF//2/Si structures and the fabrication of MOSFET's are performed at temperatures below 800 degree C. For the growth of Si films, a new growth method, which involves in situ deposition of a thin ( less than equivalent to 10nm) Si onto the CaF//2 surface at room temperature prior to deposition of Si at elevated temperatures, has been developed in order to prevent interfacial reaction between deposited Si and underlying CaF//2. Al gate n-channel MOSFET's, which are electrically isolated from the substrates, have been fabricated by utilizing plasma enhanced CVD SiO//2 as the gate insulator. The maximum field effect mobility of about 180 cm**2/V multiplied by (times) s has been obtained.
