2021 7th International Workshop on Low Temperature Bonding for 3D Integration (LTB-3D).
GaN-on-Diamond high electron mobility transistors were successfully fabricated by surface-activated room-temperature bonding technique. Various diamond substrates were finely polished and bonded to GaN-HEMTs by surface-activated room-temperature bond

To fast remove the surface damage layer from single-crystal-diamond, we have developed a chemical etching process using molten KCl and KOH solution at high temperature around 1100 °C. High removal rate about R {001} = 2.0 μm/h, R {101} = 20 μm/h a
