Abstract
A manufacturing method of a photodiode structure includes the following steps: providing a substrate; performing an epitaxial process to form a first semiconductor layer on the substrate; performing an active area patterning and etching process to form a recessed portion on the first semiconductor layer; performing a first coating process to form a first anti-reflection layer on the first semiconductor layer; and performing an ion implantation process to pass through the first anti-reflection layer and form a second semiconductor layer in the recessed portion.
