Abstract:
A planarizing method for a surface of a wafer, comprising:providing a planarization material on said surface of said wafer, said planarization material including an agent sensitive to radiation having a wavelength for inhibiting curing of the planarization material when exposed to the radiation having a wavelength for inhibiting curing; providing a substantially flat surface; contacting the planarization material on said surface of said wafer using the substantially flat surface; providing radiation having a first wavelength; exposing the planarization material on said surface of said wafer to the radiation having a first wavelength; curing the planarization material on said surface of said wafer using the radiation having a first wavelength; providing radiation having a second wavelength, said radiation having a second wavelength for inhibiting curing of said planarization material; and exposing the planarization material on said surface of said wafer to the radiation having a second wavelength causing changes to the planarization material for facilitating separation of the substantially flat surface from the planarization material on said surface of said wafer.
