Abstract:
A method for cleaning a surface on a semiconductor substrate, the method comprising:removing a hydrophilic material from a semiconductor substrate to expose an interface with a hydrophobic material; oxidizing the hydrophobic material while brush scrubbing the interface; moving the semiconductor substrate away from said brush scrubbing, into a gaseous ambient, and then into a cleaning bath, said hydrophilic and hydrophobic materials having chemical properties and being unaffected during said moving while the semiconductor substrate is exposed to an ambient humidity, an ambient temperature, and an ambient particle contamination; removing, within the cleaning bath, the oxide from the hydrophobic material; moving the semiconductor substrate from the cleaning bath, into a gaseous ambient, and then into a dryer, said hydrophilic and hydrophobic materials being unaffected during said moving from the cleaning bath; and drying, in the dryer, the hydrophilic and hydrophobic materials without oxidizing the hydrophobic material.
