Nettet25. nov. 2024 · Each measurement line was recorded in two measuring directions. Based on the two images, a minimum was calculated, minimizing the parachuting effect. Subsequently, the images were aligned using a first-order line fit. Surface roughness was calculated using the integrated roughness analysis over the whole surface of the 10 × … NettetFor uncoated samples, no line edge can be detected because the line scan has a broad proﬁle. This is independent of the acceleration voltage of the SEM, at least between values of 5 and 30kV. As the coating time increases, the signal intensity at the edge of a pattern increases, while the intensity in the middle decreases. The line edge is ...
