Low-temperature printing process

Low-temperature printing process of waterborne biodegradable polyurethanes... 

Technical issues in printed electrodes were briefly reviewed for all-printed TFT applications. Surface morphology and edge waviness of the printed electrode should be well controlled to produce uniform and stable TFT behavior and consistent thin-film device performances. This investigation fabricated solution-process TIPS-pentacene based TFT with the printed silver electrodes. Solution-process materials can be readily combined with a low-cost printing process, which can significantly reduce complexity in the fabrication and manufacturing process. In addition, these types of solution-process TFT can be fabricated at low temperatures and they can be also readily implemented on plastic substrates for flexible electronics applications. 

In summary, inkjet offers non-contact digital patterning of conductive features in an additive process with the possibUity of utilizing flexible and temperature sensitive substrates. The associated process involves low cost set-up and maintenance, provides relatively high resolution, and allows for quick turnover and customization. Overall, IJ printing wiU ultimately enable production of a broad range of electronic components that are made completely by printing processes.
