Ellipsometry on flexible substrates

Modern electronics are becoming thinner, lighter, more conformable, bendable or rollable. You now can fold your smartphone to fit in small pockets. You can wear your electronic devices to check email or monitor your daily physical activity. Augmented, Virtual and Mixed Reality (AR/VR/MR) devices allow you to experience engaging virtual or fictional reality, such as flying over the Eiffel Tower or catching virtual monsters in your backyard. This firm has received many recent requests to characterize flexible substrates, such as flexible glass, polymer sheets, metal foils and even flexible ceramics as these industries grow. In this article, we present interesting case studies demonstrating the power of spectroscopic ellipsometry for flexible substrates and their devices.
