1. A method, comprising:
- providing a substrate over which a mask material and a wavelength-converting material are positioned, wherein;
the mask material covers at least a first portion of an exterior surface of the substrate,the mask material does not cover at least a second portion of the exterior surface of the substrate, andthe wavelength-converting material is positioned over the mask material and the second portion of the exterior surface of the substrate;
removing a portion of the wavelength-converting material such that wavelength-converting material is no longer positioned over at least a portion of the mask material and at least a portion of the wavelength-converting material remains positioned over the second portion of the exterior surface of the substrate; and
after the portion of the wavelength-converting material has been removed, removing at least a portion of the mask material.
