Abstract
The main driving force behind the rapid development of plasma etching or dry etching as it is often called is today’s IC-fabrication. Practically all pattern transfer steps from the mask to the underlying substrate are performed using dry etching techniques. Due to the anisotropic nature of the etching process it is possible to obtain a much higher packing density on the surface of the IC. In addition, dry etching has a distinct advantage over liquid wet etching since it does not require large quantities of highly purified liquids which later have to be disposed requiring expensive wastewater treatment.
