Novel in-line method for patterned deposition of conductive structures

Patterned silver nanowires using the gravure printing process for flexible applications

“…A variety of roll-to-roll printing systems have been developed, and the gravure printing technique has been investigated extensively for the use in both laboratory and industrial settings because its variables are readily controlled to yield high-speed production over large areas [4][5][6][7]. The use of this technique in printed electronics requires an understanding of the printing mechanisms that yield smooth and straight lines that are suitable (and often required) for many modern devices [8].…”

High‐Performance Printed Transistors Realized Using Femtoliter Gravure‐Printed Sub‐10 μm Metallic Nanoparticle Patterns and Highly Uniform Polymer Dielectric and Semiconductor Layers

“…High‐speed roll‐based printing is particularly attractive due to its potential for very high throughput and low cost of ownership. As a result, there have been several attempts by numerous groups including our own to use various types of roll‐to‐roll printing, such as direct gravure printing, off‐set printing, and flexographic printing to fabricate printed transistors 1–6. Unfortunately, to date, the performance of such thin‐film transistors (TFTs) has been limited by the large dimensions of such printed devices (typically gravure printing produces features >50 μm), the low mobility of the printed semiconductors, and the poor electrostatic integrity of the realized devices, resulting in poor operating frequencies of demonstrated ring oscillators, ≈2.5 to 150 Hz1, 4, 5 and high operating voltages in the range of ≈50 to 100 V 1–6.…”
