IMAGE SENSORS INCLUDING PHASE DETECTION PIXEL - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18336495 Titled 'IMAGE SENSORS INCLUDING PHASE DETECTION PIXEL'
Simplified Explanation
The abstract describes an image sensor that has a pixel array with image sensing pixels and a phase detection shared pixel. The phase detection shared pixel has two phase detection subpixels next to each other. The sensor also has a color filter fence that separates the pixels and the phase detection pixel, and color filter layers are placed on the pixels and the phase detection pixel. Each image sensing pixel has a first micro-lens, and the phase detection pixel has a second micro-lens that is taller than the first micro-lens and overlaps the two phase detection subpixels.
Original Abstract Submitted
An image sensor is presented which includes a pixel array including a plurality of image sensing pixels in a substrate, a phase detection shared pixel in the substrate, the phase detection shared pixel including two phase detection subpixels arranged next to each other, a color filter fence disposed on the plurality of image sensing pixels, and the phase detection shared pixel, the color filter fence defining a plurality of color filter spaces, a plurality of color filter layers respectively disposed in the plurality of color filter spaces on the plurality of image sensing pixels, and the phase detection shared pixel, a first micro-lens disposed on each of the plurality of image sensing pixels to have a first height, and a second micro-lens disposed to vertically overlap the two phase detection subpixels of the phase detection shared pixel and to have a second height greater than the first height.
