Flare lithography
WebJul 1, 2024 · The transition to high numerical aperture (“high NA”) lithography for future process nodes will entail not only tremendous engineering innovation from the system provider (e.g., ASML), but also advanced development of suitable photoresist materials. WebThe large area wire grid polarizers (LA-WGPs) with 50 nm half-pitch were fabricated using ArF immersion lithography overcoming the limit of the shot field size. To realize the 50 nm line and space patterns on a 300 mm wafer, a zero-distance stitching process that connects the shot fields is suggested. To compensate for mutual interference between the shot …
