Printed electronics promises to enable new applications such as RFID tags, displays and various types of sensors. Critical to the development of printed electronics is the establishment of a manufacturable printing technique with high resolution and throughput. Gravure is a high-speed roll-to-roll printing technique that has many of the characteristics necessary for a viable printed electronics process...
In this paper we demonstrate the design and development of a small-size, sheet-fed gravure printer which can achieve 10 mum alignment of multiple layers and requires less than 200 muL of ink per print. Using this printer we demonstrate highly-scaled metallic silver lines, 20 mum wide, printed with nano-particle and precursor based inks. We describe some scaling trends which are specific to the printing...
In recent years, printing has received substantial interest as a technique for realizing low cost, large area electronic systems. Printing allows the use of purely additive processing, thus lowering process complexity and material usage. Coupled with the use of low-cost substrates such as plastic, metal foils, etc., it is expected that printed electronics will enable the realization of a wide range...
Printing is considered an attractive technology for realizing electronic functionality at low cost. Inkjet printing, in particular is very attractive for applications requiring low material consumption and spatially-specific material deposition. We report on inkjet-printed transistors offering performance approaching that of amorphous silicon, fabricated using nanoparticle-based metallization and...
We demonstrate printed organic transistors with sub-10V VDD . Using inkjetted nanoparticle conductors, a polymer dielectric, and a pentacene precursor semiconductor, we demonstrate devices on plastic with mobilities >0.05cm2/V-s and on-off ratios >105. Thus, for the first time, we demonstrate devices with operating specifications approaching those required for low-cost electronic systems
