摘要 |
The invention provides a method of making an electrical device, particularly a semiconductor device, having a substrate and etched electrodes formed on the substrate. The method employs flexography to print a resist pattern (7) onto a substrate (5) carrying a metal layer (8). Metal not protected by the resist can be etched away and then the resist (7) removed to leave exposed electrodes. Further materials (10, 11) can be disposed onto the exposed metal, such as organic semiconductors, to form transistors or diodes. |
