Paper Abstract

Total integrated scatter measurements, the earliest well defined measurement relating light scatter to surface roughness, is now being used in modern production facilities as a means of monitoring product surface roughness. The two applications reviewed here are computer disks, where the issue is a well defined roughness (as opposed to the smoothest possible surface) and an emerging issue with roughness specifications for the backsides of silicon wafers. The paper describes a scanning instrument that allows sample uniformity to be revealed and thus the manufacturing process investigated.
