When testing with decreased platen power on the SiO2_10 standard recipe the uniformity got very bad. I then tested with the electromagnetics coil to see if that could affect the uniformity. There is an outer coil that can be varied between 0 A and 10 A and an inner coil that can be varied between 0 A and 30 A.

I then tested with the electromagnetics coil to see if that could affect the uniformity.

The first tests were done on Si/SiO2(1µm) without pattern and measured on the ellipsometer. | ||
