Abstract: PURPOSE:To sense the tunnel current between a probe and a base board to be processed, keep the distance constant by a probe driving mechanism, and make a track groove having a uniform width and height. CONSTITUTION:The processing width, height, and length are stored in a CPU 127, and control device 126 gives commands to different parts. A bias is applied to a base board to be processed 111 from a power supply 112, and a probe 110 is approached to several nm's, and a tunnel current is allowed to flow. Via a current and voltage converter 117, logarithmic converter 118, gap control circuit 119, switch 120, and driver 125, the distance between the probe 110 and base board 110 is controlled. The moving amounts along the X-and Y-axis are measured by length measuring instruments 115, 116 and fed back to a relative displacement mechanism 114. The Z-direction feedback consists of an amount obtained by first turning on an analog switch 120. extracting a signal by a data D/A converter 123 of a memory 122, and adding thereto the desired amount of groove depth and the distance between the probe and base board by a voltage adding circuit.
