摘要:
Beam-induced etching uses a work piece maintained at a temperature near the boiling point of a precursor material, but the temperature is sufficiently high to desorb reaction byproducts. In one embodiment, NF3 is used as a precursor gas for electron-beam induced etching of silicon at a temperature below room temperature.
