Abstract:
The invention is directed toward a chemical mechanical polishing/planarizing (CMP) brush with an embedded mandrel. PVA foam injected into the substantially hollow mandrel expands through apertures in the mandrel to fill a mold in the desired shape of the brush with the foam in the mandrel being integral with the outer foam covering the brush.
