Title: Method for area-selective etching of silicon nitride layers for the manufacture of microelectronic workpieces
Inventor: SHERPA SONAM
IPC: H01L21/3065
Filed: 2019-06-24
Abstract: Disclosed embodiments provide area-selective etching of silicon nitride for the manufacture of microelectronic workpieces through sequential exposure of silicon nitride layers to hydrogen ions/radicals and then, fluorine ions/radicals followed by the same by using beam delivery techniques such as ion beam and/or neutral beam techniques. Area-selective etch processes are anisotropic when hydrogen ions are used, and are isotropic when hydrogen radicals are used. In addition, sputtering materials onto a substrate for a microelectronic workpiece is not required for the disclosed embodiments. Further, by using ion beam and/or neutral beam techniques, area-selective etching of silicon nitride is achieved in contrast with the large-area etching provided by conventional plasma processing techniques. For predetermined embodiments, the ion/neutral beam techniques described in the present specification are used to fabricate silicon nitride hard masks without requiring the use of any mask.
