Metal assisted photochemical etching (ME) of 4H Silicon Carbide (SiC) was utilized to generate locally defined porous areas on single crystalline substrates. Therefore, Platinum (Pt) was sputter deposited on 4H-SiC substrates and patterned with photolithography and lift off. Etching was performed by immersing the Pt coated samples into an etching solution containing sodium persulphate and

Deep etching of silicon carbide for micromachining …

The etch rate of 4H–SiC in a SF6 helicon plasma has been investigated as a function of pressure, rf power, bias voltage and distance between the substrate holder and the helicon source. Very high etch rates of 1.35 μm/min were achieved when this distance is minimum. Good uniformity on 2 in. SiC substrates and smooth etched surfaces free of micromasking have been obtained when using a nickel
