Jet Printing for Large Area Electronics
Abstract:The advent of new solution based organic and inorganic/organic hybrid semiconductor material along with a desire for less expensive ways to produce large area electronic devices has stimulated research into non-conventional circuit patterning methods. We report on an inkjet based printing system which was constructed to facilitate the production of etch masks and electronic devices for large area applications such as displays and x-ray sensors. A multi-ejector wax print head was integrated for high accuracy, high throughput printing of etch masks and material exclusion zones in the processing of amorphous silicon and organic electronics circuitry. The same system also utilizes specialized single ejector print heads to deposit a wide variety of organic electronic materials for rapid turn experimentation required for materials and process development. Feature sizes down to 20μm and control of feature placement below 5μm are achieved. System design and capability will be discussed in the context of the resolution, throughput, material requirements and electronic device performance.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
