Fujia Gallium said it used its proprietary vertical Bridgman (VB) method to grow
6‑inch Ga2O3 single‑crystal boules exceeding 70mm in thickness. Pinghu lab HRXRD
reported excellent crystallinity and the China Institute of Metrology confirmed
electrical properties meet SiC industry substrate requirements. Boule thickness
is a key indicator of growth maturity and industrialisation; thicker boules
allow more substrates per crystal, directly lowering per‑wafer cost.
