PURPOSE:To form on a substrate a desired pattern constituted by a layer made of an electrically conductive material, insulating material or the like, by a method wherein while being immersed in a solvent, a stencil layer is subjected to a treatment of applying ultrasonic vibrations having a frequency of 80-200kHz. CONSTITUTION:In a step of removing a stencil layer 2 from a substrate 1 as well as removing a layer 4 on the stencil layer 2 with the removal thereof, while being immersed in a solvent, the stencil layer 2 is subjected to ultrasonic vibrations having a frequency of 80-200kHz, thereby to effectively destroy a layer 6 formed attaching to the side surfaces of the stencil layer 2. Accordingly, it is possible to effectively avoid such problems that it requires a long time to obtain a desired pattern formed by a layer 3 and that a desired pattern formed by the layer 3 is obtained with an unnecessary layer 4', residues 6', 6'', 6''' and the like left thereon. Thus, it is possible to form on the substrate 1 a desired pattern constituted by the layer 3 made of an electrically conductive material, insulating material or the like. |
