Definitions for "Surface roughness"
disruption of the planarity of the semiconductor surface; measured as a difference between highest and deepest surface features; can be as low as 0.06 nm or high quality Si wafers with epitaxial layers. learn more.
the deviation of the topography of an actual surface from an ideal atomically smooth and planar surface.
the amount the surface of an optic differs from perfectly smooth, and is usually denoted as a root mean square (rms) value in Angstroms
Same as surface finish.
Surface irregularities on a machined surface. See finish, surface finish.
The fine irregularities in the surface texture which result from the production process. Consideration as vertical deviations from the nominal or average plane of the surface.
