| Research Abstract |
Single crystalized pure silicon possesses very high mechanical properties which are equivalent to those of steels, nevertheless, it is not widely applied to the mechanical component because of its difficulty to machine precisely by cutting operation.
On behalf of this, etching is often used in which anisotropic characteristic of single crystal is used. The orientation of faces to compose the shape of finished workpiece can be fundamentally decided by the anisotropic characteristic, however, the finished profile does not always coincide with that of mask, which limits the utilization of the process.
This study makes the anisotropic etching mechanism clear through the experiments under a variety of conditions, and the relation between each etching condition with the process parameters is established empirically. Then, the computer simulation of the process is established based on these relations, by which it becomes possible to foresee the finished profile for any given mask now.
