Charged Particle Beam Induced Etching |
abstract |
The present invention relates to charged particle beam induced etching. A micromachining process comprising: exposing a workpiece surface to a precursor gas, the precursor gas including a compound having an acid halide functional group; and irradiating the workpiece surface with a beam in the presence of the precursor gas, the precursor gas at Reacts in the presence of the particle beam to remove material from the workpiece surface. |
