Method for fine processing of substrate, method for fabrication of substrate, and light emitting device
First Claim
1. A method for fine processing of a substrate which comprises, after removing a single particle layer from the substrate having the single particle layer, forming a hole having an inner diameter smaller than a diameter of a particle and centering on a position on the substrate where each particle constructing the single particle layer has been placed is formed by etching.

2. A method for fabrication of a substrate, comprising the following successive steps of (I) to (V):
-
(I) forming a single particle layer by arranging particles on the substrate; (II) reducing a diameter of each of the particles by etching the obtained substrate; (III) forming a thin film composed of a mask material on the obtained substrate; (IV) removing the particle from the substrate and forming a mask having a hole with an inner diameter equivalent to the diameter of the particle at the position where the individual particle has existed; and (V) forming a hole with the diameter equivalent to the inner diameter of the hole of the mask on the substrate below the hole of the mask by etching the substrate using the mask. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
