Abstract:
A method for scaling plasma process settings from a first processing device having a first geometry and a first set of process parameters, to a second processing device having a second geometry and a second set of process parameters, the method comprising:determining a first set of plasma process settings that generates the first set of process parameters of the first processing device having the first geometry; reducing said first set of plasma process settings to isolate at least one variable on which said first set of plasma process settings depends for each plasma process setting; calculating a scaling factor for each plasma process setting from said reduced first set of plasma process settings such that the first set of process parameters substantially equals the second set of process parameters; and determining a second set of process settings for the second processing device having the second geometry by multiplying said scaling factor with each plasma process setting from the first processing device having the first geometry.
