High-Density Plasma to Achieve Fast Etching and Deposition Rates - PlasmaPro 100 Cobra

The PlasmaPro 100 Cobra® ICP system from Oxford Instruments makes use of high-density plasma to realize fast etching and deposition rates. The process modules of the system provide high-precision, high-throughput, low-damage processes and exceptional uniformity, for wafers measuring up to 200 mm.

The systems offered by Oxford Instruments have a broad install base integrated with high-volume manufacturing (HVM), as well as well-developed process solutions. The PlasmaPro 100 Cobra® is used in various fields such as GaAs and InP laser optoelectronics, MEMS and sensors, RF, as well as SiC and GaN power electronics.

  • Compatible with wafers measuring up to 200 mm
  • Electrode with a wide temperature range of −150 °C to 400 °C
  • Versatile layout and compact footprint
  • Wafer sizes can be quickly changed
  • In-situ chamber cleaning and end-pointing
  • Ease of serviceability and low cost of ownership


The Cobra® ICP etching sources yield reactive species at a high density and low pressure. An RF generator equipped in the system independently controls the substrate DC bias, thus enabling ion energy to be controlled based on the process requirements.
