Samsung Galaxy S7 teardown reveals Sony IMX260 Dual-pixel sensor
At the launch of the Samsung Galaxy S7 and S7 edge smartphones the Korean manufacturer did not provide any official information about the makers of the the new devices' camera module. However, now a teardown from technology analyst firm Chipworks has confirmed rumors that the S7 captures its images on a Sony IMX260 sensor which offers a 12MP resolution, 1.4um pixel size and dual pixel AF across the entire sensor.
Chipworks had the following to say about the process:
"Our lab staff have removed the imaging chip from the 12 MP camera module and have found a Sony back-illuminated (Exmor R) CMOS image sensor. We were expecting to find TSV arrays around the periphery of the active pixel array, corresponding to Sony’s stacked chip (Exmor RS) technology platform. Sony hasn’t publicly announced the IMX260, but based on what we’ve been reading, we assume that is the part number. It’s a bit of a surprise that the IMX260 isn’t an Exmor RS sensor, as we’ve been documenting a lot of Sony design wins based on its 1st and 2nd generation Exmor RS technology. It seems the full chip PDAF functionality, which requires dual readout from each pixel, was implemented with a multi-chip solution rather than a stacked (CIS + ISP) solution."
The measured size of the sensor is 6.69 mm x 5.55 mm (37.1 mm2) and at the front of the device there is a 5MP camera that is built around a 1.34um BSI pixel Samsung S5K4E6XP sensor.
