Microcomponents – measuring surface roughness of lithium niobate ridges

SEM (scanning electron microscope) + MountainsMap SEM software

Researchers at the FEMTO-ST Institute in Besançon, France studied methods for fabricating lithium niobate ridges to be used for the development of programmable microcomponents.

Using a scanning electron microscope they imaged ridge sides then reconstructed a 3D model of the zone with MountainsMap® SEM software.

Surface roughness (Sa) was then calculated.

Input Data
