High T/sub c/ superconducting YBa/sub 2/ Cu/sub 3/ O/sub 7-//sub x/ films were prepared by chemical vapor deposition using ..beta..-diketonates of Y, Ba, and Cu as source materials. The films were epitaxially grown on SrTiO/sub 3/ (100) substrates. The c-axis orientation perpendicular to the plane of the substrates was observed. A sharp resistive superconducting transition with T/sub c/ (R = 0) at 84 K was obtained. The maximum critical-current density at 77 K was 2 x 10/sup 4/ A/cm/sup 2/ .
