Abstract

A new phenomenon in integrated circuit etch processing is presented, explained and utilized to permit better removal of layers overlying integrated circuit structures, and if desired, the formation of conductive layers on such structures by a less complicated and lower temperature process than has been possible by conventional techniques.
