Led array

摘要

A 1200 dpi LED may be manufactured without highly accurate mask alignment and provide good light radiation efficiency. A first interlayer dielectric (12a) is formed on a semiconductor substrate (11) and has a plurality of first windows (16) formed therein and aligned in a row. A diffusion region (13) is formed in the semiconductor substrate (11) through each of the first windows (16). An electrode (14) is formed to have an area in contact with the corresponding diffusion region (13). Another electrode is formed on the other side of the substrate. A second interlayer dielectric (12b, 22b) is formed on the first interlayer dielectric (12a) such that the second interlayer dielectric (12b, 22b) does not overlap the area of the electrode (14) and does not extend to a first perimeter of the area. <IMAGE>
