WebFeb 11, 2000 · Compared to the fluorocarbons, CH 2 demonstrated better selectivity and less faceting of the TEOS hardmask. However, the profile, even before etch completion, was re-entrant even with high CH 4 flows. The double-bonded structure of the C 2 H 4 makes it a more polymerizing gas than CH 4 and subsequently a better sidewall passivant. WebThe present invention provides a ferroelectric device relatively free of fences by using a hardmask having high etching selectivity relative to an underlying barrier layer. The present invention also includes a method for suppressing the fences clinging to the sidewalls of ferroelectric devices.
