[Analysis Case] Analysis of H termination on Si surface

Qualitative and relative comparison of SiH and states on the Si surface due to differences in processing.

We compared the states of the Si surface after HF treatment and after ozone treatment. In the positive ion spectrum, the peak intensity of Si was different. The weaker Si intensity after HF treatment is due to Si being metallic, while the stronger Si intensity after UV-ozone cleaning and in the As Received state is due to Si being oxide-based. From the negative ion spectrum, fragment ions reflecting the surface state were detected: SiF, SiH, and Six series after HF treatment, and SiO2 series after UV-ozone cleaning and in the As Received state.
