200kg Sapphire Boules

What’s beyond the six-inch sapphire wafer? Rubicon has production capability for eight inch wafers today, and with these 200-kg boules, we are advancing to 12-inch sapphire substrates.

Just as the semiconductor industry got its start with two-inch silicon wafers back in the 1960s and has now scaled up to twelve-inch (300 mm) wafers, there is a parallel trend in sapphire substrates for LEDs and other electronic applications. Larger wafers provide significant efficiencies in MOCVD reactor processing, providing much greater throughput per reactor run, reducing edge loss, and taking advantage of available back-end processing equipment.
