摘要： Provided are a finger type photodiode and a method of manufacturing the same, which can reduce noise by forming a shallow doping layer. The finger type photodiode includes a bottom substrate supporting layers to be formed thereon, an epitaxial layer formed on the bottom substrate, a finger doping layer formed in a finger shape on a top surface of the epitaxial layer, and a shallow doping layer formed with a shallow depth on an externally exposed top surface of the epitaxial layer and a top surface of the finger doping layer. Since the dangling bond generated on the epitaxial layer and the finger doping layer is reduced, noise can be reduced, thereby improving the light efficiency and reliability of the photodiode.
