Abstract: Purpose: Microcontact printing is a process used to print high resolution protein arrays for biosensors. We investigate using these techniques to print electrically conductive fine line structures for electroluminescent (E/L) light sources. Approach: The viability of using microcontact printing as a process for electronics fabrication is investigated. Polydimethylsiloxane (PDMS) stamps inked with alkanethiol compounds form Self Assembled Monolayers (SAM) on substrate surfaces, acting as the resist to subsequent etching processes. The printed lines are characterized with regard to their performance as high electric field generators in electroluminescent displays. Findings: It has been demonstrated that microcontact printing is a cheap, repeatable process for fabricating electronic devices. The results demonstrate the viability of the process to fabricate electric field generator structures for E/L light sources with reduced driving voltages. Value: It has been demonstrated that microcontact printing can produce electrically conductive fine-line structures with high resolution, confirming its viability in printed electronics manufacture.
