    The superconducting transition temperatures (TC) of (1 1 1) and (0 0 1) boron-doped diamond films deposited by microwave plasma assisted chemical vapor deposition (MPCVD) are investigated in the wide boron concentration range of 1 × 1020 - 1 × 1022 cm-3. The critical boron concentrations of superconductor to insulator transition in (1 1 1) and (0 0 1) films are 3 × 1020 cm-3. TC in (1 1 1) films does not have the tendency to saturate up to 1 × 1022 cm-3, while TC in (0 0 1) films saturates.
