IMAGE SENSOR INCLUDING COLOR FILTER GRID INCLUDING PORTION OVERLAPPING SUPER PHASE DETECTION (PD) PIXEL - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18216170 Titled 'IMAGE SENSOR INCLUDING COLOR FILTER GRID INCLUDING PORTION OVERLAPPING SUPER PHASE DETECTION (PD) PIXEL'
Simplified Explanation
The abstract describes an image sensor with different pixel regions and lenses. It includes a substrate with two surfaces, a first pixel region, a second pixel region, and a third pixel region. The first lens is placed on the first pixel region, while the second lens is on the second and third pixel regions. An element separation film is present in the substrate between the first and second pixel regions. A first color filter allows light focused by the second lens to pass through to the second and third pixel regions. The first pixel region has a width between 0.5 um and 0.9 um in a specific direction, and the first lens is located on the second surface, which is parallel to that direction.
Original Abstract Submitted
An image sensor a substrate comprising a first surface and a second surface opposite to the first surface; a first pixel region; a second pixel region; a third pixel region; a first lens on the first pixel region; a second lens on the second and third pixel regions; an element separation film provided in the substrate and interposed between the first pixel region the second pixel region; a first color filter configured to transmit light focused by the second lens to the second pixel region and the third pixel region; and a color filter grid forming a region in which the first color filter is provided. A width of the first pixel region in a first direction is between 0.5 um and 0.9 um. The first lens is disposed on the second surface. The first direction is parallel to the second surface.
