While plasmas using mixtures of SF₆, C₄F₈, and Ar are widely used in deep silicon etching, very few studies have linked the discharge parameters to etching results. The authors form such linkages in this report. The authors ...
In process optical emission spectroscopy (OES) measurements, excitation mechanisms as dictated by the process plasma can be complex to analyze optical signals quantitatively. Applications of a new electron beam excitation ...
