| Research Abstract |
Polycrystalline silicon carbide microstructures were fabricated by micromachining for microsensors in order to estimate the promising properties as a material for micromachining. Microdiaphragms and microbidges were fabricated by micromachining of the polycrystalline silicon carbide film on the single crystal silicon substrate.
The polycrystalline silicon carbide film were deposited on (100) surface of single crystal silicon wafer by low pressure chemical vapor deposition at about 1000 degree C.The source material was tetramechisilane (TMS). The silicon carbide microdiaphragms and microbridges were fabricated by reactive ion etching of silicon carbide films and anisotropic etching of silicon substrate.
Microsensors were prepared using these structure. The deformation of the diaphragm by the applied pressure was detected optically with optical fibers connected to the diaphragm. The microbridge was useful as a infrared micro-light source.
