A method for forming a luminescent layer on a light emitting semiconductor
device includes positioning a stencil on a substrate such that a light
emitting semiconductor device disposed on the substrate is located within
an opening in the stencil, depositing a stenciling composition including
luminescent material in the opening, removing the stencil from the
substrate, and curing the stenciling composition to a solid state. The
resulting light emitting device includes a stack of layers including
semiconductor layers comprising an active region and a luminescent
material containing layer having a substantially uniform thickness
disposed around at least a portion of the stack. A surface of the
luminescent material containing layer not adjacent to the stack
substantially conforms to a shape of the stack. In one embodiment, the
light emitting device emits white light in a uniformly white spatial
profile.
