Bird View. Dark area is Silicon. Bright area is Silicon Dioxide. The edges are nicely defined, though corrugated on the 100 nm scale.

Close up. Bird View. Dark area is Silicon. Bright area is Silicon Dioxide. Residues of the SiO2 etching are apperent on top of the SiO2, i.e. particles a few nanometers in diameter. Most probably it is sputtered and redopsited Silicon Dioxide, but not confirmed. Attempts to remove them in 7-Up or HCl failed.
