In this report, a new process for patterning of YBaCuO thin films, ICP(inductively coupled plasma) method, is described by comparing with existing wet etching method. Two 100㎛ wide and 2mm long YBaCuO striplines on LaAlO$_3$ substrates have been fabricated using two patterning techniques. And the properties were compared with the critical temperature and the SEM photography. Then, the critical temperatures of two samples were about 88 K, but the cross section of sample using ICP method was shaper than that using the wet etching method. ICP method can be used as a good etching technique process for patterning of YBaCuO superconductor.
