ABSTRACT:
Minute structures are obtained by exposing a process target material and changing the shape thereof by relatively shifting a laser beam or electron beam against the process target material and simultaneously repeating irradiation in an intermittent manner. A plurality of minute convex or concave shapes are formed on the process target material by employing a branching element for branching a single beam into a plurality of beams; a parallel element for converting said plurality of beams into beams which respectively advance in parallel; and a condensing element for condensing the plurality of beams to the process target material and generating a plurality of minute spots thereon.
