We report on the fabrication of YBCO-Josephson-junctions using a narrow-focused Ga-ion beam to damage the MgO-substrates prior to film deposition. On top of the micro-areas damaged by the ion-beam, the as-grown YBCO-film shows weak-link properties. The final junction was achieved using photolithogra
