Spin Curve
The thickness is measured on VASE Ellipsometer using a simple Cauchy model for a transparent polymer on Si. The measurements are performed at one incidence angle (70 degrees) only.
9 points on each 4" wafer has been measured; the standard deviation thus representing the homogeinity of the film on the 4" wafers.
