WebThe present invention has disclosed a method for in-situ aberration measurement in an optical imaging system of lithographic tools, which comprises the steps of: imaging the reticle pattern by the beams transmitting through the reticle via the optical imaging system; using particular tools to measure plural groups of linewidths by modifying the intensity … WebOptical Lithography. Photolithography is a patterning process in which a photosensitive polymer is selectively exposed to light through a mask, leaving a latent image in the polymer that can then be selectively dissolved to provide patterned access to an underlying substrate. From: Nanocoatings and Ultra-Thin Films, 2011. Webk1 is a factor that accounts for the processing characteristics such as the quality of the resist and the use of resolution enhancement techniques like off-axis illumination. k1 has a theoretical minimum of 0.25, although values below 0.3 are considered too difficult or expensive for common use. citizens bank of americus mobile app
