Development of Polarization Imaging Sensing Technology for Controlling the Quality of Printed Electronics Manufacturing

摘要

Printed electronics has manufacturing advantages such as low environmental load and low cost in addition to the characteristics of the device itself such as flexibility and transparency, which cannot be achieved in conventional semiconductor devices. As research and development on printed electronics increases, there are high expectations for Roll-to-Roll (R2R) production in which devices are made on a film using coating and printing technology. In order to continuously produce devices on the film which is being rolled up in R2R production, non-contact, high-speed sensing equipment is required. Through collaborative research with Yamagata University, we found that the crystallinity of the organic semiconductor layer is crucial for securing device quality, and we developed polarization in-line sensing technology that can visualize the crystallinity of the organic semiconductor layer in-line for achieving R2R production.
