One of the feed lines may be at a first condition, and the other may be at a second condition that is different from the first condition. The relative amount of rinsing solution provided to the bath by each feed line may be varied to continuously vary the condition within the bath.

  • Patent number: 8951430
    Abstract: Methods of metal assisted chemical etching III-V semiconductors are provided. The methods can include providing an electrically conductive film pattern disposed on a semiconductor substrate comprising a III-V semiconductor. At least a portion of the III-V semiconductor immediately below the conductive film pattern may be selectively removed by immersing the electrically conductive film pattern and the semiconductor substrate into an etchant solution comprising an acid and an oxidizing agent having an oxidation potential less than an oxidation potential of hydrogen peroxide. Such methods can form high aspect ratio semiconductor nanostructures.
