    摘要: In some implementations, a method is provided for inhibiting charge damage in a plasma processing chamber during a process transition from one process step to another process step, including performing a pre-transition compensation of at least one process parameter so as to inhibit charge damage from occurring during the process transition. In some implementations, a method is provided for inhibiting charge damage during a process transition from one process step to another process step, which includes changing at least one process parameter with a smooth non-linear transition. In some implementations, a method is provided which includes sequentially changing selected process parameters such that a plasma is able to stabilize after each change prior to changing a next selected process parameter.

    摘要: In some implementations, a method is provided in a plasma processing chamber for stabilizing etch-rate distributions during a process transition from one process step to another process step. The method includes performing a pre-transition compensation of at least one other process parameter so as to avoid unstable plasma states by inhibiting formation of a parasitic plasma during the process transition. In some implementations, a method is provided for processing a workpiece in plasma processing chamber, which includes inhibiting deviations from an expected etch-rate distribution by avoiding unstable plasma states during a process transition from one process step to another process step.
