Patent and technology consultancy Chipworks has published its iPhone 7 teardown and reveals that front and rear image sensors on the new Apple models are supplied by market leader Sony. This is not too much of a surprise as earlier iPhone models used Sony sensors as well. In its report Chipworks doesn't say which exact sensor model has been deployed in the rear camera but we know the 12MP chip uses the Exmor RS technology platform, a Bayer RGB color filter array and on-sensor phase detection. Its die size is 5.16 mm x 6.25 mm (32.3 mm2) as measured from the edges of the die stack. 

On the FaceTime front camera the resolution has been increased to 7MP. The Sensor is also a second generation Sony Exmor RS model and measures 5.05 mm x 3.72 mm (18.8 mm2). Chipworks has not treated the larger iPhone 7 Plus model with its dual-camera to the teardown procedure yet, but we would expect both sensors in the dual-camera to come from Sony as well. For now you can find more technical detail in the iPhone 7 teardown on the Chipworks blog.
