Title: Optical device wafer processing method
Inventor: KOYANAGI OSAMU
IPC: B23K26/57
Filed: 2018-08-28
Abstract: To reduce chippings and cracks and the like generated in an optical device layer.SOLUTION: There is provided an optical device wafer processing method for transferring an optical device layer of an optical device wafer to a transfer member. The optical device wafer processing method comprises a division groove forming step, a transfer member joining step, a laser beam irradiating step, and a crystalline substrate peeling step. The division groove forming step forms a division groove which does not completely segment a buffer layer of the optical device wafer on the optical device layer side along division schedule lines. The transfer member joining step joins the transfer member to a surface of the optical device layer. The laser beam irradiating step irradiates the crystalline substrate with a pulse laser beam of a wavelength having permeability and the buffer layer with a pulse laser beam of a wavelength having absorptivity from the rear surface side of the crystalline substrate. The crystalline substrate peeling step peels the crystalline substrate from the optical device layer and transfers the optical device layer to the transfer member. The laser beam irradiating step alters a buffer layer remaining without being segmented by the division groove forming step or the buffer layer and a part of the optical device layer.SELECTED DRAWING: Figure 3
