Abstract:
A silicon wafer after being cleaned by using a cleaning liquid is rinsed by using carbonic water. According to such a silicon wafer cleaning method, generation of static due to a rinsing treatment is not caused, so that an electrostatic breakdown is not caused, adhesion of dirt to a cleaned silicon wafer surface due to the static is not caused, adhesion of metal impurities can be prevented in the rinsing treatment of the silicon wafer and, while giving consideration to the cost, furthermore, a rinsing treatment using a clean rinsing liquid free from causing any residue can be performed.
