Characterization of Photo-reduced Silver Organometallic Salt Deposited by Inkjet Printing
Abstract:The use of ink jet printing to produce metallized patterns on temperature-sensitive substrates is attractive for applications such as printed electronics and MEMS. Silver (in either suspension or solution) is a widely investigated material for such inks due to high conductivity when compared to alternatives such as conductive polymers. The use of silver nanoparticle suspensions enables processing temperatures as low as 150 °C, with conductivity approaching that of the bulk material. Work presented within demonstrates the use of a silver organometallic salt dissolved in xylene that can be printed readily and undergoes photolysis to elemental silver when exposed to a 514 nm laser. Conductive tracks produced by this method are characterized to demonstrate their use for metallization at near room temperature with a feature resolution below 10 μm.

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.
