Photodiode for ultra high speed optical communication and fabrication method therefor |
摘要 |
Disclosed is a photodiode having a p-type electrode of a mushroom shape. The p-type electrode is formed in a mushroom shape, so that the contact area faced by the spreading region of a dopant for the photodiode and the electrode can be minimized and the capacitance of the photodiode can be reduced. Further, the p-type electrode is configured to have a broader width in its upper end, thus allowing the wire bonding to be performed easily.
