Anisotropic etching (reactive ion etching) used in achieving better resolution and tolerances of photoresist geometry does not etch an RIE induced coating from the sidewalls of a particular topology. The combination of anisotropic and isotropic etching resolves this problem without impact on resolution and tolerances.
