Zusammenfassung:A three dimensional (3D) device is formed from a first level and a second level that are attached together. The first level includes a backside illuminated two dimensional (2D) image sensor including an array of first pixels sensitive to visible light. The second level includes a frontside illuminated depth sensor including an array of second pixels sensitive to near infrared light. The first and second levels are attached in a manner such that radiation, in particular the near infrared light, received at the backside of the first level passes through the first level to reach the depth sensor in the second level.
