Holding unit, processing apparatus and holding method of substrates
摘要:
A holding unit holds a substrate to enable a surface of the substrate to be processed. The unit has a vacuum suction member that comes into contact with a peripheral portion of the surface of the substrate and sucks the substrate. A processing apparatus holds the wafer stably and allows an edge, a bevel portion and/or a back surface of the wafer to be processed.
