Microphotoelectrochemical etching of n-GaAs by focused He-Ne laser was inven-stigated. An etched pattern was scribed on the n-GaAs surface while the sample moved in X-Y two directions by means of two motors controlled by microcomputer. The diameter of the etched holes was 2 μm. The intensity of the laser light, the concen-trations of different etchants, such as KOH, _2SO_4, HCl and KCl etc., the etching time, the electrode potentials effected the diameters and depths of the etched holes. The experiment results were discussed and analyzed in this paper.
