| Summary: | 碩士 === 國立中正大學 === 機械系 === 93 === This thesis completes and realizes a new microfabrication method called “open channel capillary molding” that was initially proposed by T. Y. Peng of the Nano/Micro Science and Engineering research group at the Department of Mechanical Engineering of National Chung Cheng University. The main feature of the method includes a unique ability to discretely create linearly patterns of different materials on a single substrate. Based on this open channel capillary molding method, an innovative fabrication for full color polymeric light emitting diodes (PLEDs) is proposed. Compared with existing methods of PLED fabrication, specifically, the inkjet printing and spin coating, the new open channel capillary molding process enjoys not only the advantages of simplicity and low setup cost as spin coating but also capability of full color fabrication and minimum or no material wastes as the inkjet printing. PLED devices using different electroluminescent materials, MEH-PV and PF, were successfully demonstrated with a feature size of 200 um.
