Abstract:
The invention is an plasma processing system with a plasma chamber for processing semiconductor substrates, comprising: a radio frequency or microwave power generator coupled to the plasma chamber; a low pressure vacuum system coupled to the plasma chamber; and at least one chamber surface that is configured to be exposed to a plasma, the chamber surface comprising: a Y x O y F z  layer that comprises Y in a range from 20 to 40%, O in a range from greater than zero to less than or equal to 60%, and F in a range of greater than zero to less than or equal to 75%. Alternatively, the Y x O y F z  layer can comprise Y in a range from 25 to 40%, O in a range from 40 to 55%, and F in a range of 5 to 35% or Y in a range from 25 to 40%, O in a range from 5 to 40%, and F in a range of 20 to 70%.

Claim (Index 6):
The method of  claim 5 , further comprising:\n controlling a composition of the Y x O y F z  layer to achieve a target yttrium hydroxide particle generation in the plasma processing chamber and a target etch rate of the substrate.
