Claim Text:
1. A superhydrophobic substrate comprising: a plurality of protrusions having a pseudo random distribution corresponding to a voronoi diagram on one surface thereof, an average interval between respective protrusions among the plurality of protrusions being greater than an interval between light beam wave peaks of light within the visible spectrum, wherein an interval between respective protrusions among the plurality of protrusions adjacent to one another satisfies a normal distribution, wherein the average interval between respective protrusions among the plurality of protrusions is within a range of 0.4 μm to 100 μm, wherein a standard deviation of the normal distribution is within a range of 1/20 to ¼ of an average value of the normal distribution, wherein a diameter of the protrusions is within a range of 5% to 30% of the average interval between the respective protrusions among the plurality of protrusions, and wherein a height of the plurality of protrusions is within a range of 15 to 90% of the average interval between the respective protrusions among the plurality of protrusions.
