Abstract

A method of manufacturing wavelength converting members includes: disposing masks having a rectangular shape in plan view on an upper surface of a wavelength converting substrate; singulating the substrate into workpieces, each including an upper surface and lateral surfaces, with a predetermined size and a rectangular shape in plan view such that the upper surface includes one of the masks and a portion of the substrate; aligning a predetermined number of the workpieces and disposing a light-shielding film on the lateral surfaces and the upper surface of each workpiece, and on the mask of each workpiece; removing the masks with portions of the light-shielding film on the masks, while maintaining a portion of the light-shielding film on the upper surfaces of the workpieces at portions surrounding the masks; and reducing a thickness of a portion of each workpiece where the mask has been removed.
