Shape control using hologram-assisted talbot lithography
2021
In recent years, unique functions of nano-periodic structures have attracted much attention, and there is a need for
processing techniques with high processing efficiency and flexibility. Therefore, we focused on Talbot lithography, which
has excellent processing efficiency for periodic structures. In this paper, we use hologram-assisted Talbot lithography to
improve the processing flexibility of Talbot lithography. Hologram-assisted Talbot lithography is a method to improve
the processing flexibility of structures by using CNN to estimate the incident light distribution. In order to improve the
accuracy of the hologram-assisted Talbot lithography method for controlling periodic structures, we studied the learning
of CNN. And we showed that the shape and period of the structure can be controlled by using CNN.
