Abstract: This paper details the creation of 3-dimensional (3-D) microstructures in 4H-silicon carbide (4H-SiC) substrates with a plasma etch process that utilizes multilayer etch masks. An inductively coupled plasma (ICP) etch process (SF 6 /O 2) for SiC was developed and etch rates as high as ~1 μm/min, a selectivity of 60:1 (SiC to Ni), and aspect ratio dependent etch characteristics were
We have investigated the etching of SiC using inductively-coupled-plasma reactive ion etching with SF6-based and Cl2-based gas mixtures. Etch rates have been investigated as functions of bias voltage, ICP coil power, and chaer pressure. It will be shown, for the first time, that SiC surfaces etched in Cl2-based plasmas yield better surface electrical characteristics than those etched in SF6

The etch rate of the polycrystalline β-silicon carbide (SiC) substrate in a wide range from less than one to more than ten µm/min is studied using chlorine trifluoride gas at concentrations of 10-100% in aient nitrogen at 673-973K and atmospheric pressure in a horizontal reactor.
2019/7/8· To deposit and etch the silicon carbide waveguide on silicon oxide, Ma first used electron beam lithography to pattern the waveguides and reactive ion dry etching to remove excess silicon carbide. But his first attempts using a typical polymer-based mask didn’t work because the process removed more of the mask than the silicon carbide.

If silicon nitride is being used as a mask for silicon etching, potential etching of the silicon nitride need not be taken into consideration. KOH etching of silicon dioxide is observable. The etch rates are considerably slower (1-2 orders of magnitude) than that of silicon but should be considered when deep etching is being done.
