Ellipsometry (SE) + Transmittance (T): Thickness accuracy much improved
-
SE+T provides much more accurate thickness, n,k properties than those measured by SE alone
-
Additional information (such as gradience) could be obtained

Thickness accuracy
much improved
SE + T + Res (sheet resistance)
-
SE+T+Res provide more accurate thickness, n,k
-
Additional information that could be obtained accurately,
-
Gradience
-
Carrier density
-
Carrier mobility
