Light emitting device, method of manufacturing wavelength converting member and method of manufacturing light emitting device

A method of manufacturing a plurality of wavelength converting members, the method comprising:

• disposing a plurality of masks having a rectangular shape in a plan view on an upper surface of a wavelength converting substrate;
• singulating the wavelength converting substrate into a plurality of singulated members, each including an upper surface and lateral surfaces, with a predetermined size and a rectangular shape in a plan view such that the upper surface of each of the plurality of singulated members includes one of the plurality of masks and a portion of the wavelength converting substrate;
• aligning a predetermined number of the singulated members and disposing a light-shielding film on the lateral surfaces and the upper surface of each of the singulated members, and on the mask of each of the singulated members;
• 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 singulated members at portions surrounding the masks;
• and
• processing the singulated members whose masks have been removed, the processing comprising reducing a thickness of a portion of each of the singulated members where the mask has been removed to obtain the plurality of wavelength converting members.

A method of manufacturing a plurality of wavelength converting members, the method comprising:

• disposing a plurality of masks on an upper surface of a wavelength converting substrate;
• disposing a light-shielding film on portions of the upper surface of the wavelength converting substrate that are not covered by the masks and on upper surfaces of the plurality of masks;
• singulating the wavelength converting substrate into a plurality of singulated members each including an upper surface and lateral surfaces which are cross sections of the wavelength converting substrate, with a predetermined size and a rectangular shape in a plan view such that the upper surface of each of the plurality of singulated members includes portions corresponding to one of the plurality of masks and a portion of the wavelength converting substrate,
• 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 singulated members surrounding the masks;
• and
• processing the singulated members whose masks have been removed, the processing comprising reducing a thickness of a portion of each of the singulated members where the mask has been removed to obtain the plurality of wavelength converting members.

A method of manufacturing a light emitting device, the method comprising:

• providing a wavelength converting member, the wavelength converting member including
• a first upper surface and a second upper surface,
• a lower surface located at an opposite side from the first upper surface and the second upper surface,
• at least one first lateral surface connecting the second upper surface and the first upper surface, and
• at least one second lateral surface connecting the second upper surface and the lower surface, wherein
• a first thickness between the lower surface and the first upper surface is smaller than a second thickness between the lower surface and the second upper surface, and the second upper surface is covered by a light-shielding film;
• bonding the wavelength converting member with at least one light emitting element having a light-extracting surface and lateral surfaces such that the lower surface of the wavelength converting member and the light-extracting surface of the at least one light emitting element face each other;
• and
• disposing a covering member on the second lateral surface of the wavelength converting member and the lateral surfaces of the at least one light emitting element.
