A PREDICTIVE METHOD OF MATCHING TWO PLASMA REACTORS

Etch rate distribution non-uniformities are predicted for a succession of hardware tilt angles of the RF source applicator relative to the workpiece, and the behavior is modeled as a non-uniformity function for each one of at least two plasma reactors. An offset Δα in tilt angle α between the non-un...
