Superconducting quantum devices have been a widely studied topic for the last few decades due to the potential they possess. The fundamental circuit element of such devices are Josephson junction, which works with the principle of Josephson effect. Josephson junction provides the nonlinearity needed for superconducting quantum devices, and allows us to fabricate such devices using basic circuit elements. Consequently, to be able to further progress in developing superconducting devices, high v quality Josephson junctions are required; to be able to fabricate high quality Josephson junction, a precise and repeatable fabrication process is needed. In this thesis, fabrication and characterization of Josephson junctions are conducted to investigate the important parameters affecting the quality of junctions, in order to help optimize a fabrication process that is precise and repeatable. The theory and theoretical characteristics of Josephson junction are discussed; the detailed fabrication process, the results, the discussion on the lessons learned and future work is presented.
