In this communication we report some of the features of the heteroepitaxial growth of c-axis-oriented YBa2Cu3O7/SrTiO3 multilayer thin films on (100) SrTiO3 substrates, produced by high pressure oxygen DC- and RF-sputtering. The growth morphology was investigated by high-resolution electron microscopy. Several thickness of the insulating material were tested to investigate the ability of SrTiO3 to homogeneously and epitaxially cover a YBa2Cu3O7 bottom layer. The quality of the individual layers and their interfaces are discussed.
