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 and outer coil that can be varied between 0 and 10A and an inner coil that can be varied between 0 and 30 A. The first tests were don on Si/SiO2(1µm) without pattern and measured on the ellipsometer. | |||
