Abstract
The growing demand to manufacture, with high accuracy, structures enabling medical diagnostic tests on polymer disposable devices introduces the needs to improve manufacturing technology including in-line quality verification. This paper focuses on hot embossing as a process suitable to replicate nano test structures on thermoplastic substrates. A metrological approach based on calibrated AFM measurements allows for process optimization and equipment calibration. Bulk deformation measurements are used as a surrogate for dimensional variation of the replicated test structures to enable real time cycle-to-cycle process and product dimensional control. Scatterometry measurements were performed to demonstrate future possibilities for in-line post process nano-scale dimensional quality control.
