Semiconductor Lithography (Photolithography) - The Basic Process

WebImmersion lithography uses a pool of ultra-pure water between the lens and the wafer to increase the lens's numerical aperture (NA) – a measure of its ability to collect and focus light. With conventional 'dry' lithography, NA can only reach about 0.93. Immersion made it possible to create systems with an NA up to 1.35. WebThe standard steps found in a lithography module are (in sequence): dehydration bake, HMDS prime, resist spin/spray, soft bake, alignment, exposure, post exposure bake, develop hard bake and descum.
