(If either … Witryna1 paź 2024 · Insect roughness, paint chips, and erosion were characterized then manufactured. In the tests, these roughness configurations were recreated as distributed roughness, a forward-facing step, and an eroded leading edge. Distributed roughness was tested in three heights and five densities. Chord Reynolds number was varied …

Witryna11 cze 1999 · The results indicate that molecular weight is a significant factor influencing the magnitude and type of line-edge roughness at low aerial image contrast. Interferometric lithography affords the unique ability to independently control dose, pitch and aerial image contrast during photolithographic exposure. In this report, we … Witryna7 cze 2016 · Line edge roughness (LER) refers to the randomly varied edges of gate patterns, or the roughness of the printed pattern edge. As the minimum feature size … graph acceleration vs time
Aerial image contrast using interferometric lithography: effect on …
Witryna25 kwi 2003 · An off-line image analysis algorithm and software is developed for the calculation of line-edge roughness (LER) of resist lines, and is successfully compared with the on-line LER measurements. The effect of several image-processing parameters affecting the fidelity of the off-line LER measurement is examined. The parameters … Witrynaroughness (that is, the edge variance) per unit spatial frequency. For a type of roughness called “white” noise, the PSD is a constant for all spatial frequencies. But … WitrynaA simple model of how roughness maps to device performance is also presented. 1. INTRODUCTION AsshowninCobb,et.al.1 and elsewhere2−6 resist line edge roughness (LER) is typically dominated by spatial frequencies lower than roughly 20 to 30 cycles/micron. The rms roughness, σLER, on the other hand, is typically on the order … graph accountenabled
