Zusammenfassung: | An image sensor includes a semiconductor material with a photodiode disposed in the semiconductor material. The image sensor also includes a transfer gate electrically coupled to the photodiode to extract image charge from the photodiode in response to a transfer signal. A floating diffusion is electrically coupled to the transfer gate to receive the image charge from the photodiode. At least one isolation structure is disposed in the photodiode, and the at least one isolation structure extends from a surface of the semiconductor material into the photodiode. |
