Abstract

An apparatus for forming a predetermined circuit pattern on a circuit substrate by using a .mu.-STM write head, the .mu.-STM write head comprising a write head substrate having a flat surface, a plurality of micro chip electrodes formed upright on the flat surface of the write head substrate and constituting a .mu.-STM, a level of a distal end of each of the chip electrodes being set to be constant, and scanning means for scanning the micro chip electrodes on the circuit substrate by moving the micro chip electrodes and the circuit substrate relative to each other in two-dimensional directions.
