Thermal-mechanical characteristics and outgassing efficiency of integrated in-plane outgassing channels (IPOCs) at Al2O3-intermediated InP (die)-to-Si (wafer) bonding interface is investigated. The IPOCs are introduced and investigated via both multi-physics simulation and experimental demonstration. Thermal stress simulation indicates that Al2O3 bonding layer efficiently mitigates the [...]

Silicon Carbide Circuits on the Way
Although silicon is the semiconducting material of choice in the majority of applications in electronics, its performance is poor where large currents at high voltages have to be controlled. For about 50 years, scientists have been eyeing silicon carbide [...]
PAM-XIAMEN offers lapped silicon carbide wafers, As-cut wafers are lapped and cleaned to be qualified as lapped wafers. What is wafer lapping? Wafer lapping is a global flattening process that improves wafer flatness by removing surface damage (usually from back grinding). It is most commonly found [...]
