sf 6is an op- timum gas to generate the F radicals that etch and thus efficiently remove the de - posits on the walls of the plasma cham - ber. This process is known as ‘chamber cleaning’. Gas purity is of key importance in this market segment, because any possibility of contamination has to be minimized.
