제목 Fabrication of patterned electroluminescent polymers with soft lithography
초록 For most practical applications, it is essential to fabricate micro- or nanoscale polymer electroluminescent (EL) devices and pixel arrays. Although several methods to pattern EL polymers have been used previously: photolithography, laser ablation, and ink-jet printing, these techniques have limitations such as damage of EL materials.
Whitesides group [1] has introduced a new powerful technique, ‘soft lithography’, that has been developed as an alternative to photolithography for micro- and nanofabrication. This technique uses a patterned elastomer (usually PDMS) as the mold, stamp, or mask to generate or transfer the pattern. Soft lithography offers immediate advantages over photolithography and other conventional microfabrication techniques. Here we describe a method of patterning polymeric EL materials based on microcontact printing (mCP) and micromolding in capillary (MIMIC) using PDMS stamp. Prior to the patterning, we found out the optimum condition of the surfaces of the substrate and the mold for the patterning. Therefore, we fabricated the patterns of the polymeric EL materials.
