Lithography using alternating phase shift mask – Ansys Optics

WebA method of phase shift lithography includes forming a chromeless phase shift reticle with a pattern of parallel, spaced phase shifters. The phase shift reticle is placed between an exposure source (e.g., UV light) and a substrate having a layer resist formed thereon. Following an initial exposure, the phase shift reticle is rotated and the substrate is … WebA novel polymer‐layer‐free system for liquid‐crystal alignment is demonstrated by various shaped indium tin oxide (ITO) patterns. Liquid crystals are aligned along the ITO line pattern and secondary sputtering lithography can change the shape of the ITO line pattern. Different shapes can control the direction and size of the pretilt angle.
