>Dear members,
>
>       Does anyone have background information of how black silicon can
>be formed in RIE system? In my case, see black silicon on silicon wafer
>after long (more than 10mins) CF4/H2 plasma exposure. The surface is also
>powdery with this black stuff. If you know anything about it or any good
>reference paper, would you please let me know? Thanks a lot.
