ICP etching is a widely used technique to deliver high etch rates, high selectivity and low damage processing. Excellent profile control is also provided as the plasma can be maintained at low pressures. The Cobra® ICP etcher sources produce a high density of reactive species at low pressure. Substrate DC bias is independently controlled by an RF generator, allowing control of ion energy according to process requirements.
