“The first GaN on GaN LED is now available on the market” announces Yole Développement

SORAA Tri LED &Lightchip analysis is a complete teardown of the LED and the package with detailed
photos, material analysis, detailed structure of dies and package, manufacturing process flow, in-depth economic analysis, manufacturing cost breakdown and selling price estimation.

This reverse costing study has been conducted in order to give insight on technology data,
manufacturing cost of the Light chip and the 36 Tri-LED in the MR16-50-B01-12-830-25 MR16 lamp
from SORAA. The tri-LED component is a LED in GaN on GaN. The Lightchip is a silicon based wafer
level packaging.

SORAA has released the first GaN on GaN LED in a 50W halogen equivalent MR16 lamp with several
new features. “We estimate that SORAA design and manufacture the GaN on GaN LED and the silicon
based wafer level package in their factories in California”, explains Michel Allain, CEO, System Plus
Consulting.

SORAA smartly used the GaN characteristics like the optical transparency and the high electrical and
thermal conductivity to create a unique vertical structure for these LEDs. The layers deposited by
epitaxy are very thin. A high current density per sq cm is obtained, estimated at 120A/sq cm. The
SORAA LEDs have a triangular shape to limit the internal reflection of the light and thus increase the
light extraction. Each LED measure 0.07 sq mm.

An original silicon package with a multilayer mirror is used to increase the light extraction of the LED
lamp.
