WebWe report the development of a high aspect ratio inductively coupled plasma (ICP) etch process for 4H-SiC. Feature sizes as narrow as 2 μm were etched at a rate of 0.18 μm/min, with an etch rate as high as 0.43 μm/min measured as feature size was increased to 10 μm. Aspect ratios above 10 were routinely obtained using an electroplated Ni mask.
