| description | Disclosed is a method of manufacturing a master mold having an uneven pattern which includes wide and narrow concave portions using a reactive ion etching process. The method is capable of manufacturing a master mold improved in the uniformity of concave portions of the uneven pattern by performing a main etching step in which etching is performed, using an original plate which includes a processing target layer and a foundation layer, on the processing target layer using the foundation layer as an etch stop layer and an extra etching step in which etching is performed on the original plate degraded by the main etching step in the uniformity of concave portions in order to improve the uniformity using an etching gas which includes a first gas capable of etching the foundation layer and producing a deposit with a bias power of not greater than 15 W. |
