Abstract
The influence of interface charges on the properties of Si-Si and Si-SiO2 interfaces prepared by direct bonding has been investigated. Surface potentials of N-N and P-P interfaces and recombination currents in P-N junctions depend on surface and heat treatments. In both cases lower magnitudes were measured in samples pre-treated in HF compared to samples pre-treated in HNO3. Bonded Si-SiO2 interfaces with interface state densities of about 1011 cm-2 eV-1 and low flatband voltages have been achieved.
