Abstract
An ambit light sensor with a function of IR sensing and a method of fabricating the same are provided. The ambit light sensor includes a substrate, an ambit light sensing structure, an infrared ray (IR) sensing structure, and a dielectric layer. The ambit light sensing structure is located over the substrate for sensing and filtering visible light. The IR sensing structure is located in the substrate under the ambit light sensing structure for sensing IR. The dielectric layer is located between the ambit light sensing structure and the IR sensing structure.
