We present a quick survey of the properties of Josephson junctions and a few strategies used to fabricate them with cuprate high temperature superconductors. As an example, we show our recent results on ramp-edge junctions where both superconducting electrodes and the barrier are based on electron-doped cuprates. These superconducting-normal-super-conducting junctions obtained in the ramp-edge geometry present current-voltage characteristics, field dependence of the critical current and Shapiro steps in ambient RF field confirming their quality. They can be used to study the proximity effect through electron-doped barriers with different doping levels.
