Abstract:
The present disclosure, in some embodiments, relates to a brush cleaning apparatus. The brush cleaning apparatus includes a wafer support configured to support a wafer. The brush cleaning apparatus also includes a cleaning brush including a porous material coupled to a core material. An uppermost surface of the porous material defines a planar cleaning surface. A first nozzle is configured to apply a first cleaning liquid directly between the wafer and the planar cleaning surface of the cleaning brush.
