IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240274629 titled 'IMAGE SENSOR
The abstract describes an image sensor with a pixel separation region that includes insulating and conductive layers to improve performance.
- The image sensor has a substrate with a pixel separation recess.
- Photo-sensing elements are arranged in the substrate.
- The pixel separation region fills the pixel separation recess.
- The pixel separation region includes a first insulating layer covering the inner wall of the recess.
- A first conductive layer covers at least a portion of the side surface of the first insulating layer.
- A second insulating layer covers a portion of the side surface of the first conductive layer within an inner space defined by the first conductive layer.
- A second conductive layer fills the remaining space not filled by the second insulating layer and is connected to the first conductive layer.
Potential Applications: - Digital cameras - Smartphones - Surveillance systems - Medical imaging devices
