Embodiments of the invention include a semiconductor structure including a light emitting layer. The semiconductor structure is attached to a support such that the semiconductor structure and the support are mechanically self-supporting. A wavelength converting material extends over the sides of the semiconductor structure and the support. In some embodiments, a thickness of the wavelength converting material on a side of the semiconductor structure is at least 25% of a thickness of the wavelength converting material over a top of the semiconductor structure.
