Historically, photolithography has used ultraviolet light from gas-discharge lamps using mercury, sometimes in combination with noble gases such as xenon. These lamps produce light across a broad spectrum with several strong peaks in the ultraviolet range. This spectrum is filtered to select a single spectral line. From the early 1960s through the mid-1980s, Hg lamps had been used in lithograph… WebNov 27, 2016 · I am a professional with extensive expertise in the field of 3D NAND memory, specifically in photolithography and integration processes.
