The article reviews the development over the past six years in the thin-film growth and junction fabrication of superconducting MgB2 materials, including future prospects for MgB2 superconducting electronics. The most serious problem in the thin-film growth of MgB2 is the high Mg vapour pressure required for phase stability. This problem has made in-situ film growth difficult. At present, however, high-quality in-situ films can be prepared either by a low-temperature route or a high-temperature route. Current best films substantially exceed bulk single crystals in size and quality. The technology to fabricate MgB2 junctions has also shown great progress, and now all-MgB2, SIS Josephson junctions are realized, which demonstrates a great potential for MgB2 in superconducting electronics.
