US4666555A - Plasma etching of silicon using …

A method of plasma etching silicon using a fluorinated gas mixture. A mixture of CHF3 and SF6 is utilized in an etch chaer to form a plasma for etching silicon. The degree of anisotropy of the etch can be controlled by changing the percentage of CHF3 in the CHF3/SF6 mixture. The method does not adversely affect the etched surface so that no post-etch thermal process step is required to cure
