It is known that a high performance micro system for the medical treatment, biotechnology, and nanotechnology etc, become a system where the electric circuit and the sensor are integrated on flat surface and spherical surface etc. In the future, anisotropic etching for spherical single-crystal silicon can be a key technique in order to develop a higher performance micro system. This paper has investigated the result of microstructure fabrication in spherical single-crystal silicon by anisotropic etching, and proposed a selection indicator in the line direction of mask pattern (crystal orientation), which is corresponded to users.

In this system, the functions of position control and NC have been expanded based on surface observation function of friction force microscope (FFM). Precision positioning of cantilever was possible by using the displacement sensor in this system. Newly machining cantilever1with high stiffness was developed, and spinous single diamond grain was bonded on the end of this cantilever. Cantilevers for machining and measuring were able to exchange alternately. By using this system, 3D nano-machining and measuring was achieved.
