Abstract
A light source including a die, substrate, and droplet of encapsulating material is disclosed. The die includes a semiconductor light-emitting device that is connected to first and second conducting traces on a first surface of the substrate. The droplet of encapsulate material overlies the die and is formed from a liquid precursor material that is characterized by a surface tension. The droplet has a periphery in contact with the first surface, the periphery having a shape determined by a predefined feature on the first surface and the surface tension of the liquid precursor material. The feature can include a recess in the first surface or a ring having an area that is raised above the first surface.
