IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17901335 titled 'IMAGE SENSOR
Simplified Explanation
The abstract describes an image sensor with a stack structure that includes an active pixel region and a pad region. The stack structure consists of multiple substrates and structures, including a photoelectric conversion region, a floating diffusion region, a pixel gate, and a logic transistor.
- The image sensor has a stack structure with an active pixel region and a pad region.
- The stack structure includes multiple substrates and structures.
- Each pixel in the active pixel region has a photoelectric conversion region and a floating diffusion region.
- The pad region has a pad opening that allows for access to the pad.
- The pixel gate is electrically connected to the floating diffusion region in each pixel.
- The logic transistor is included for driving the pixels.

Original Abstract Submitted
An image sensor includes a stack structure including an active pixel region in which a plurality of pixels are defined, and a pad region arranged on at least one side of the active pixel region. The stack structure includes a first substrate including a photoelectric conversion region and a floating diffusion region in each pixel, a first semiconductor substrate, a first front structure on the first semiconductor substrate, and a pad opening penetrating the first semiconductor substrate in the pad region, a second substrate attached to the first substrate and including a pixel gate electrically connected to the floating diffusion region in each pixel, a third substrate attached to the second substrate and including a logic transistor for driving the plurality of pixels, and a pad having a top surface that is exposed through the pad opening.
