Abstract: An article having alternating oxide layers and nitride layers is etched by an etch process. The etch process includes providing a first gas comprising C4F6H2 in a chamber of an etch reactor, ionizing the C4F6H2 containing gas to produce a plasma comprising a plurality of ions, and etching the article using the plurality of ions.
