Title:
LIGHT-EMITTING DEVICE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2021064698
Kind Code:
A
Abstract:
To provide a method for manufacturing a light-emitting device capable of simply forming a reflection wall of a double structure whose inside is a white wall and outside is a black wall.SOLUTION: A first groove 20 is formed by half dicing. A depth of the first groove 20 may be such a depth as to penetrate through a sealing resin 13 and not to penetrate through a substrate 10. Subsequently, a white resin is injected to the first groove 20 to be embedded in the first groove 20, and is cured so that a white wall 15 is formed. Subsequently, a second groove 21 is formed by half dicing. A width of the second groove 21 is made narrower than a width of the first groove 20, and a center in a width direction of the second groove 21 is set to coincide with a dividing line L. A depth of the second groove 21 is set at such a depth as to penetrate through the white wall 15 and not to penetrate through the substrate 10. Subsequently, a black resin is injected to the second groove 21 to be embedded in the second groove 21, and is cured so that a black wall 16 is formed. Subsequently, dicing is performed, and it is separated into individual light-emitting devices.SELECTED DRAWING: Figure 3
