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. | |||
