Electrons, not Ions, Provide Superior Plasma Etching of …

Due to the mostly vertical delivery of reactive ions, RF plasma etching can produce anisotropic etching useful to fabrie relatively sharp corners, flat surfaces and deep cavities. However, “When ions with over 1000 volts of energy hit the surface,” explains Professor Goddard “You get a couple of nanometers of damage automatically, even in the best case.”

An approach of fabriing pseudoperiodic antireflective subwavelength structures on silicon carbide by using self-asseled Au nanopatterns as etching mask is demonstrated. The nanopatterning process is more time-efficiency than the e-beam lithography or nanoimprint lithography process. The influences of the reactive-ion etching conditions and deposited Au film thickness to the subwavelength

Anisotropic Etching of SiC Whiskers | Nano Letters

We have demonstrated a method of producing nanoplatelets or complex well-ordered nanostructures from silicon carbide (SiC) whiskers. Preferential etching of SiC whiskers in a mixture of hydrofluoric and nitric acids (3:1 ratio) at 100 °C results in the selective removal of cubic SiC and the formation of complex structures reseling a pagoda architecture. Possible mechanisms governing
