Overview

he Dektak 3 Surface Profilometer is an instrument to measure the vertical profile of samples, thin film thickness, and other topographical features, such as film roughness or wafer bowing. A diamond stylus is moved vertically into in contact with the sample and then moved laterally across the sample for a specified distance and specified contact force. The instrument can measure small surface variations in vertical stylus displacement as a function of position. The Dektak profilometer can measure small vertical features ranging in height from 100 Å to 650,000 Å on a 5″ Diameter Sample Stage.
