摘要： A method and system to clean and rinse and dry wafer comprises a precision control of an outward-moving inner boundary condition and a steady state edge boundary condition. The edge boundary condition can confine the liquid within the substrate by an edge liquid flow step, to create an outer liquid boundary, to confine the liquid within the wafer, and to compensate for liquid lost through process conditions such as wafer spinning. The outward-moving inner boundary condition can control or distribute the liquid within the substrate by an inner liquid boundary condition that moves outward to the edge of the wafer, to create an outward-moving inner liquid boundary, to uniformly distribute liquid within the wafer, and to uniformly drying the wafer.

摘要： A polishing apparatus includes a rotatable head assembly including a substrate retainer that incorporates a cavity in the face surface of the substrate retainer for temporarily holding polishing slurry during operation of the polishing apparatus. The cavity resides in the face surface of the substrate retainer at a location adjacent the perimeter surface of the retainer. During operation of the polishing apparatus, slurry flowing along the surface of the polishing pad flows into the cavity where a portion of the slurry is temporarily held. As the head assembly of the polishing apparatus rotates against the polishing pad, slurry continuously flows from the cavity across the polishing pad and is uniformly distributed across the exposed surface of the substrate being polished. An offset in the cavity wall permits used slurry to flow away from the substrate retainer during rotation of the head assembly.
