The roughness types are distinguishable by the scattering out of the diffraction orders [ 13, 20] as predicted by Fourier optics using binary gratings [ 20 ]. cork and screw mankato mn3.1 Line Edge Roughness (LER) LER can be measured by high resolution critical dimension scanning electron microscopes (CD-SEMs). In order to obtain the amount of LER, the local position of the line edge is first measured at regular intervals (i.e., Δ). Then, the average edge and the standard deviation of the … Se mer When considering LER, any roughness in mask patterns would appear to be a root-cause of LER. If mask patterns themselves have LER, and lithography techniques are able to transfer that LER without distortion, the … Se mer The resolution achieved in lithography techniques primarily depends on the size of projection lens used, because the aperture (or diameter) of the projection lens determines the … Se mer Even though other sources of LER can be excluded, intrinsic non-uniformities in photoresists cause LER along the side edges [18]. For instance, even if there is no variation in exposure light intensity, the photon absorption of … Se mer In CMOS fabrication, chemical amplification is exploited to increase the sensitivity of the photoresist.
