The electron stimulated desorption signature of a HF etched Si(100) su
rface has been examined in this study. Hydrogen passivation results in
strong H+ and H- desorption signals. Both F+ and F- species are elect
ronically desorbed, although no fluorine is observed in Auger electron
spectroscopy. Low current density argon ion sputtering results in sig
nificant changes in the H+ and H- energy distributions which suggest a
n ion induced change in hydrogen adsorbate structure.
