Patent ID: 7504667

Claim:
A light emitting diode of the semiconductor lamination structure comprising at least: an n-type semiconducting layer, an active layer composed of 30 or less quantum well layers, a p-type semiconducting layer provided on a substrate, wherein the surface of said semiconductor lamination structure contains a flat portion and bores; the in-plane coverage rate of said bores is 10% or more without exceeding 85%; the opening of said bore has a diameter of 100 nm or more without exceeding 4000 nm; the depth of said bore is smaller than the distance between said active layer and said flat portion; and the density of said bores expressed in terms of number of bores is 8×10 5 per/cm 2 or more without exceeding 1.08×10 10 per/cm 2 , and a transparent conductive film covering a plurality of said bores.
