摘要:
A light-emitting element (24) is disclosed. A light emitting diode (LED) includes a sapphire substrate (26) having front and back sides (33, 35), and a plurality of semiconductor layers (28, 30, 32) deposited on the front side (33) of the sapphire substrate (26). The semiconductor layers (28, 30, 32) define a light-emitting structure that emits light responsive to an electrical input. A metallization stack (40) includes an adhesion layer (34) deposited on the back side (35) of the sapphire substrate (26), and a solderable layer (38) connected to the adhesion layer (34) such that the solderable layer (38) is secured to the sapphire substrate (26) by the adhesion layer (34). A support structure (42) is provided on which the LED is disposed. A solder bond (44) is arranged between the LED and the support structure (42). The solder bond (44) secures the LED to the support structure (42).
