摘要
A scanning tunneling microscope tip has been used to selectively write oxidation patterns on a thin Si3N4 film on p(+) silicon. After etching the patterns in hydrofluoric acid, trenches are observed, consistent with silicon consumption in the oxidation process. The patterns in the nitride film could be transferred to the underlying silicon with an ammonium fluoride etch.
