Web6 de abr. de 2024 · In this work, we optimize a CH 3 F/O 2 /He/SiCl 4 chemistry to etch silicon nitride gate spacers for 3D CMOS devices in a 300 mm inductively coupled plasma reactor. The chemistry has high directivity and high selectivity to Si and SiO 2.A cyclic approach, which alternates this chemistry with a CH 2 F 2 /O 2 /CH 4 /He plasma, is … WebView history. A hardmask is a material used in semiconductor processing as an etch mask instead of a polymer or other organic "soft" resist material. Hardmasks are necessary when the material being etched is itself an organic polymer. Anything used to etch this material will also etch the photoresist being used to define its patterning since ...
