Pyrolyzed Photoresist as a Continuous‐Tone Mask for Grayscale Lithography

Advanced Science, EarlyView.
True grayscale contact photolithography masks are created by pyrolysis of 3D multiphoton resist patterns. The resulting carbon masks retain micrometer‐scale patterned features while providing continuous‐tone optical transmission. This approach provides access to high‐quality grayscale lithography without requiring exotic materials or commercial mask ...
