Abstract
A photodiode balanced in increased sensitivity and speed. The photodiode includes a semiconductor substrate, an active region formed on the semiconductor substrate, and a comb electrode connected to the active region. The comb electrode includes a plurality of electrode fingers, and each of the electrode fingers includes a transparent electrode contacting the active region, and an opaque electrode formed on the transparent electrode. Here, the width of the opaque electrode is set smaller than the width of the transparent electrode.
