Patent ID: 7312161

Claim:
A method for providing low variability surface treating of at least one semiconductor device to be treated on at least one surface thereof in an immersion process, comprising: a) determining a Desired Treatment Amount of the at least one semiconductor device; b) determining an Intermediate Target Treatment Amount from the formula: Intermediate Target Treatment Amount=Desired Treatment Amount−Predicted Termination Treatment Amount, wherein the Predicted Termination Treatment Amount is a predicted amount of final treatment that will occur during execution of a predetermined treatment termination protocol; c) initiating treatment of at least one semiconductor device in a treatment bath with a treating component; d) calculating the amount of treatment and treatment rate of the at least one semiconductor device at least a first time T 1 ; e) determining a time T T in the treatment process to initiate the predetermined treatment termination protocol to achieve the Intermediate Target Treatment Amount based on the calculated amount of treatment and treatment rate of step d); and f) executing the treatment termination protocol at the time T T determined in step e).
