Woollam M-2000UI

Function

The Woollam ellipsometer is used for measuring the thickness of transparent layers. Ellipsometry particularly useful to measure the thickness of thin transparent layers and to measure the optical constants of a layer. The automated XY stage is used to measure the nonuniformity of the parameters across the wafer.
