We investigate the use of microsystems (MEMS) in the direct patterning of materials needed for organic optoelectronic devices on large area low-cost substrates.

We present a new high-resolution printing technique for depositing molecular organic semiconductor materials on substrates. By depositing the materials directly from the gas phase, without liquid phase coming in contact with the substrate, we aim at avoiding the limitations encountered when inkjet printing such materials.

One of the main advantages of this technique is that it does not require a vacuum, which is very significant for achieving lowcost fabrication.

Our micromachined printhead was used, in conjunction with inkjet technology for the delivery of liquid phase material, to print patterns of organic material.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
