Combining the pressure sensor’s oxidation insulating?nanostructure fabrication this paper studied the impact of bias
voltage, ambient temperature and humidity on the size of oxide?dots during the AFM-based anodic oxidation nano-fabrication.?Experimental results show that the size of oxide dots increases?with the increasing bias voltage and ambient humidity, but too?high bias voltage and ambient temperature will cause staircase?phenomena on the surface of oxide dot; ambient temperature?22 ??, bias voltage 8V, humidity 50% and oxidation time 8s are?relatively suitable processing parameters for the oxidation?fabrication of n-type Si (100).
