摘要： The present invention relates to an avalanche photodiode having a guard ring structure for reducing edge-breakdown thanks to an external voltage applied through a metal pad attached on the guard ring and a manufacturing method thereof. The avalanche photodiode having a guard ring structure includes: a plurality of semiconductor layers which are stacked on a substrate; an active area which is formed on part of the top of the semiconductor layers; a guard ring which is formed on the top of the semiconductor layers, is separated from the active area, and has a ring shape surrounding the active area; and a connection unit which is formed on the top of the semiconductor layers and is connected to the guard ring to apply an external voltage onto the guard ring. Therefore, the external voltage is applied onto the guard ring of the avalanche diode through the connection unit so that edge-breakdown can be reduced.
