Silicon carbide has very stable characteristics, so that it can work stably in some harsh environments. Because of the stable chemical bonds, the technical threshold for silicon carbide production is very high. The growth conditions of silicon carbide crystal ingots are harsh, requiring high temperature (~2600℃) and high [...]

Ge/SiO2 direct wafer bonding by O2-plasma pretreatment was investigated. The bonding interfaces of Ge/SiO2 low temperature direct wafer bonding were characterized by transmission electron microscopy. The perfectly atomic level Ge/SiO2 bonding was achieved after a 1500C annealing for 60 hours. The excessive O2-plasma exposure resulted in micro-crack [...]
