Back-to-back solid state lighting devices and associated methods

A method of forming a solid state light (SSL), comprising:

• providing a carrier substrate having a first electrically insulative material at a first surface of the carrier substrate, a second electrically insulative material at a second surface opposite the first surface, a first through substrate interconnect (TSI) extending from the first surface to the second surface, and a second TSI extending from the first surface to the second surface;
• disposing a first reflective material in direct contact with the first electrically insulative material;
• mounting a first solid state emitter (SSE) over the first reflective material and overlapping the first TSI and electrically coupling the first SSE to the first and second TSIs;
• disposing a second reflective material in direct contact with the second electrically insulative material;
• and
• mounting a second SSE over the second reflective material overlapping the first TSI and electrically coupling the second SSE to the first and second TSIs.
