    • PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor optical device by which a monolithic semiconductor lens having a desired shape is easily formed.
      SOLUTION: In this method of manufacturing the semiconductor optical device, a mask pattern 46 formed on an imprint resin layer 42 by a nano-stamper 43 is transferred to the other surface side of a semiconductor substrate 21 to form the monolithic semiconductor lens 23. Since this method allows the mask pattern 46 of high precision to be formed on the imprint resin layer 42 by impression of the nano-stamper 43, the monolithic semiconductor lens 23 having a desired shape is formed more easily than conventional methods which use wet etching or form resist patterns by baking. In addition, the shape of the monolithic semiconductor lens 23 has good reproducibility.
