We have successfully fabricated freestanding single-crystal 6H-SiC cantilevers of several microns size using bulk micromachining with an inductively coupled plasma reactive ion etching system. We have also used these SiC cantilever structures to measure Young's modulus through the use of an atomic force microscope. The measurements were performed on a series of 13 νm thick and 20 νm wide cantilevers with lengths ranging from 100 νm to 350 νm. The average measured Young's modulus of 441 GPa is in excellent agreement with the documented values in the literature.
