Abstract
An image sensor structure includes a substrate, a first infrared filter, a second infrared filter, a planarization layer, a color filter and a third infrared filter. The substrate has a first sensing region for detecting visible light and a second sensing region neighboring the first sensing region for detecting infrared light. The first infrared filter is disposed on the first sensing region. The second infrared filter is disposed on the second sensing region and neighbors the first infrared filter. The second infrared filter defines one or more openings for penetrating incident light. The planarization layer is over the first infrared filter and the second infrared filter, and fills the one or more openings. The color filter is on the planarization layer and vertically above the first sensing region. The third infrared filter is on the planarization layer and is vertically above the second sensing region.
