Wearable electronics, particularly soft strain sensors with direct skin adhesion, play a crucial role in applications such as smart healthcare systems and human-machine interfaces. However, existing approaches for developing dry-adhesive...
Deformation of a LCD glass-panel during the alignment is analyzed for a UV-nanoimprint lithography process. In UV-nanoimprint processes for manufacturing LCD panels, a glass-panel should be aligned with respect to the position of fiducial marks on imprint mold and the target glass. The alignment process will place the nano-patterns on the mold into the designated position in the glass-panel. Usually, viscoelastic resin is laminated between the mold and glass-panel. The resin is solidified by ultra-violet light and is designed to be nano-patterns. Thus, shear force would be induced on the panel during alignment process. The shear force can cause deformation of glass-panel, which ultimately causes misalignment of nano-patterns. Thus, deformation analysis for the glass-panel in the alignment process is essential to enhance the accuracy and to reduce alignment cost in nano-imprint. In this work, deformation of the glass panel from the viscous force is calculated by using 'ALGOR' package. The mechanism of misalignment of nano-patterns due to the deformation is analyzed. Finally, the effect of misalignment is discussed, and the experimental results are also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
