Superconducting MgB2 thin films have been fabricated on originally prepared boride substrates(AlB2(0001), ZrB2 (random orientation), CaB6(0001), Al2 O3(0001) by pulsed laser deposition (PLD) at room temperature, followed by in-situ annealing process. The highest Tc of 30K, transition width of 6K was obtained for Al2 O3(0001). Tcs were lowered and no zero resistivity was observed for boride substrates.
