摘要： In a semiconductor light emitting device, a semiconductor light emitting element has a light extracted surface on which a plurality of convex structures is formed. The convex structures each have a conical mesa portion constituting a refractive index gradient structure, a cylindrical portion constituting a diffraction grating structure, and a conical portion constituting a refractive index gradient structure. The mesa portion, cylindrical portion, and conical portion are arranged in this order from the light extracted surface. The period between the convex structures is longer than 1/(the refractive index of an external medium+the refractive index of the convex structures) of an emission wavelength and equal to or shorter than the emission wavelength. The circle-equivalent average diameter of the cylindrical portion is ⅓ to 9/10 of that of the bottom of the mesa portion.

摘要： The present invention provides such a formation method that an antireflection structure having excellent antireflection functions can be formed in a large area and at small cost. Further, the present invention also provides an antireflection structure formed by that method. In the formation method, a base layer and particles placed thereon are subjected to an etching process. The particles on the base layer serve as an etching mask in the process, and hence they are more durable against etching than the base layer. The etching rate ratio of the base layer to the particles is more than 1 but not more than 5. The etching process is stopped before the particles disappear. It is also possible to produce an antireflection structure by nanoimprinting method employing a stamper. The stamper is formed by use of a master plate produced according to the above formation method.
