What Are the Challenges in Implementing Roll-to-Roll NIL?
Despite its advantages, R2R NIL faces several challenges:
Alignment Issues: Ensuring precise alignment between the mold and the substrate can be difficult, particularly for complex patterns. Material Compatibility: Finding resist materials that are both effective for imprinting and compatible with the substrate can be challenging. Wear and Tear: The continuous nature of the process can lead to wear and tear of the molds, necessitating frequent replacements. Process Control: Maintaining consistent pressure, temperature, and speed throughout the process is crucial for uniform patterning.
