Lithography k1
WebII. Pattern-Dependent Litho/Etch Variability In modern projection lithography, the numerical aperture (NA) of the scanner optical system is increasing and is above 1 in the case of immersion lithography. Simultaneously, the k1 factor (normalized line width k1=CD/(O/NA), where CD is minimum feature size, O the wavelength) is steadily decreasing http://www.lithoguru.com/scientist/litho_papers/1993_37_Understanding%20Focus%20Effects_Review.pdf

WebJ-STAGE Home 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.
WebThe physical limit lithography is k 1 = 0.25. Smaller critical dimension can be achieved by using a combination of smaller light wavelength and larger numerical aperture (NA), … The periodic enhancement in the resolution achieved through photolithography has been a driving force behind Moore's Law. Resolution improvements enable printing of smaller geometries on an integrated circuit. The minimum feature size that a projection system typically used in photolithography can print is given approximately by: where

Page 2 The Fluid Refractive Index WebK1 factor decrease – K1 factor was 0.6-0.7 in production environment – Today most aggressive k1 in production is 0.3 –Physical limit for single exposure is 0.25 – Using DE/DP k1 could be pushed down to 0.22 ÎThis will allow to print features less than ¼ of the exposure wavelength
WebEUV lithography will be able to provide a significant relaxation in lithographic K1 factor (and a corresponding simplification of process complexity) vs. existing 193nm lithography. The increased K1 factor will result in some complexity reduction for mask synthesis flow elements (including illumination source shape optimization, design pre-processing, RET, …
