WebFor typical photoresists and film thicknesses we achieve a uniformity of better than 5%. The speed can be set from 1-12,000 rpm, time 0.1-99999 sec/step. Vacuum can also affect film uniformity in some processes. Vacuum can be set on or off. We offer mechanical chucks for non-vacuum applications. WebThe film uniformity for 30 nm thickness shows more than 10%, while that for the thickness of more than 50 nm indicates less than 5%, suggesting that measurement on 30 nm thick film using Filmetrics F50 is not still accurate enough. Standard deviation and coefficient of variation are also examined to discuss the film uniformity. Keywords
