Zusammenfassung: | PURPOSE: To provide an apparatus and method of planarizing a wafer surface, without using the mechanical polishing. CONSTITUTION: A fluid insulation material is applied to treating surfaces of wafers 24-31, the wafers are laid on the inner side faces of a tubular wall of a planarizer 10 with their treating surfaces facing the center axis of the planarizer, the planarizer is rotated to exert a centrifugal force on the treating surfaces to uniformly distribute the insulation material over the wafer surfaces. |
