WitrynaSPI surface finish chart for roughness technology SPI a1 is comparable to RA.0-1 made by #3 diamond buff SPI a2 is slightly finer than a1 and RA.1-2 made by #6 diamond buff SPI a3 has more imperfections than a2 and RA.2-3 made by #15 diamond buff . SPI b1 is finer than a3 and RA.2-3 made by 600 grit WitrynaThe main industry work horse for in-line roughness measurements is the CD-SEM, however, today no adequate reference metrology tools exist that allow to evaluate its roughness measurement sensitivity and precision. To bridge this gap, in this work the roughness measurement capabilities of different analytical techniques are investigated.
