Abstract
A light source apparatus and a fabrication method thereof can prevent light interference between light emitting devices adjacent to each other by forming a groove in a sub-mount and bonding a light emitting device to the groove, enhance heat radiating effect as well as luminous efficiency by collecting light emitted from the side of the light emitting device toward the front of the light source apparatus, reduce the process time and costs and increase reliability by directly connecting the sub-mount to the stem by the first electrode and the second electrode which pass through holes of the sub-mount, and extend a life span of the light emitting device because of the enhanced heat radiating effect.
