Abstract  T$'$-phase electron-doped superconductor Pr$_{1 -x}$LaCe$_{x}$CuO$_{4 - \delta }$ (PLCCO) thin films are successfully prepared on SrTiO$_{3}$ (100) substrates by using the dc magnetron sputtering method. It is found that the films each have a highly oriented structure along  the $c$-axis. For optimally doped films with $x \approx 0.10$, the superconducting transition temperature $T_{\rm c}$ is 23.5 K, which is similar to that of a single crystal. The quadratic temperature dependence of the  resistivity is observed when $T>T_{\rm c}$, which can be attributed to the two-dimensional Fermi liquid behaviour. Besides, the optimal conditions for preparing the T$'$-phase PLCCO thin films are also discussed in detail.
