Thin films with lesser defects

ID: F1601-03

Nano-scale slim films have become an important component of numerous products. Novel optical technology to detect and repair defects during production will improve quality and durability, and increase competitiveness. Tiny defects in slim movies utilized in items such as polymer-coated paper and low-cost, flexible photovoltaics (PVs) can decrease product quality and durability. This additionally decreases yield and increases scrap levels, more impacting competitiveness. Exposure of such defective PV modules and polymer-coated paperboard barrier movies to water vapour causes short circuits in electronics and the degradation of paper items. In-line quality control examination systems alleviate some of the burden, but there's frequently a trade-off between quality and speed. As a new task nears completion, experts have actually developed revolutionary optical strategies for existing optical measurement systems that detect smaller defects faster. Gas cleaning after examination has been introduced whereas cleaning and localised fix to eliminate particles produced during manufacturing will be introduced in the next phase. Laboratory tests have actually demonstrated a really promising decrease in problem densities of more than 90 %. One demonstrator and one proof-of-concept detection system have been implemented for each line. Ongoing trials are creating excellent results and the final demonstrators will showcase the new detection, cleaning and repair technologies. The technologies will be integrated with modern high-throughput roll-to-roll processing to increase production performance and decrease production expenses. Improved defect detection and fix will improve the quality and life time of products employing large-area thin movies, improving the competitive position of manufacturers. It'll also reduce waste, decrease costs and translate to crucial advantages for the environment. Brand new markets in smart packaging, flexible electronics and large-area lighting can be expected for the companion organizations.
