<p>A substrate cleaning device is capable of removing more diverse contaminants from substrates than ultra-low temperature aerosol ejection, while avoiding technical problems inherent to wet cleaning, such as micro-roughness, watermarks, loss of substrate material and destruction of the device structure. A substrate cleaning device for cleaning wafers to which cleaning target objects have adhered includes a cluster spraying unit which sprays the wafer with one or more types of clusters formed of cleaning preparation molecules agglomerated together, a suction unit which sucks the cleaning target objects separated by spraying the clusters of the cleaning agent molecules; and a unit for moving the wafer and the cluster spraying unit relative to the one another along the surface of the wafer W to which the cleaning target objects have adhered.</p> |
