(57) [Problem] To uniformly apply a phosphor-containing material to an LED. A method for forming a light emitting layer on a light emitting semiconductor device according to the present invention includes positioning the stencil on the substrate so that the light emitting semiconductor device provided on the substrate is located in an opening of the stencil. Performing, and depositing a stencil composition containing a luminescent material on the opening, and removing the stencil from the substrate, Curing the stencil composition to a solid state. The resulting light emitting device includes a stack of layers including a semiconductor layer with an active region, and a light emitting material containing layer provided around at least a portion of the stack and having a substantially uniform thickness. . The surface of the luminescent material-containing layer that is not adjacent to the stack substantially matches the shape of the stack. In one embodiment, the light emitting device emits white with a uniformly white spatial profile. |
