Patent ID: 8253422

Claim:
A method for the manufacture of wafers, comprising: providing a production process for cleaning, rinsing and drying production wafers that include micro devices having micro features formed on or in a dielectric film, said production process providing a low resource solution in terms of solution and energy consumed subject to a constraint that each said cleaning, rinsing and drying process reach a specified impedance condition of the wafers' micro features within a specified time constraint, said reaching of the specified impedance condition based on in-situ impedance measurements of micro features in an electro-chemical residue sensor (ECRS) that are representative of the micro features on the production wafer, said ECRS used only during design of the production process; and processing production wafers through the cleaning, rinsing and drying processes controlled in accordance with the low resource solution of the production process, said production wafers processed without the ECRS.
