WebSiC substrates are higher cost than Si but have been successfully used for LED manufacturing processes. Much of the LEDs produced by Cree (who also manufacture SiC substrates) use this type of substrate. However, the higher cost and limited availability of 6 inch SiC material means that the majority of LED producers use sapphire. WebFeb 15, 2024 · Single-crystal sapphire (α-alumina, Al 2 O 3) is an excellent material for gallium nitride (GaN) epitaxial substrates and is the most common substrate material used in light-emitting diodes (LEDs) [1,2,3,4,5].However, with sapphire as a substrate for GaN epitaxy, lattice mismatch is a fatal problem.
