Mask-less Patterning Technology for the Printed Electronics Market
Abstract:Non-impact printed electronics is an expanding market with a large variety of applications where printing technology will be used to produce devices or components on glass or polymer films such as organic LED's, (organic) solar cells, displays and RFID tags. We will describe a unique and new printing technology which enables maskless patterning of surfaces or coatings on thin (insulating) substrates. For volume production of many applications in printed electronics, very thin, patterned layers of (semi-)conducting and/or insulating polymers need to be created with high precision and extremely uniform thickness. Printing of such layers can result in significant cost reductions compared to other techniques. InnoPhysics is developing a micro plasma printing system, which can be installed on existing (inkjet) printing platforms. It can be used for substrate surface energy controlled inkjet printing but also for direct etching and deposition of thin layers. To be more specific and valuable many emerging applications demand hybrid manufacturing utilizing both slot-dye coated forms and inkjet for which etching and activation in one machine are mandatory. Deposition is under further research. We will describe the technology behind ‘plasma printing’, developed applications for surface energy contrast patterning and selective ink wetting and planned future developments, making use of the new technology for the creation of functional materials on flexible substrates.

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.
