Pulsed laser deposition was used to grow high-quality Y-Ba-Cu-O (YBCO) and CdS thin films sequentially on MgO. A temperature window between 200 and 250 {degree}C was found to be suitable for the deposition of CdS on YBCO. The transition temperature of the heterostructure was measured to be 72 K while the single YBCO film had a {ital T}{sub {ital c}} of 85 K. The degradation was determined to be due to interface reaction, rather than the result of poor deposition conditions. X-ray measurements indicated that the CdS film was hexagonal and {ital c}-axis oriented. {ital In} {ital situ} resistivity measurement was used to monitor the film growth dynamics.
