Continuous Inline Metrology of Roll-to-Roll Micro-Contact Print Process
Xian Du, Jingyang Yan, Rui Ma (University of Massachussets Amherst)
To solve inline metrology problems in quality monitoring and controlling the R2R micro-contact print process, we proposed a real-time imaging technique based on controlled condensation figures and closed-loop feedback image registration. Our experimental results showed that the method can achieve high-precision pattern metrology for a continuous R2R print process.
