Research and Markets (http://www.researchandmarkets.com/research/h6gc5h/apple_iphone_5s) has announced the addition of the "Apple iPhone 5S Camera Module 8Mpixel 1.5µm Stacked BSI CIS from Sony - Technology Analysis" report to their offering.
For the iPhone 5S iSight camera module, Apple continues to integrate a 8Mpixel resolution CMOS Image Sensor. They achieve to obtain 33% increase in light sensitivity by improving the camera aperture from f/2.4 to f/2.2 and by rising the pixel size from 1.4µm to 1.5µm.
The unique technology from Sony (Exmor-RS) allows to raise the pixel array size by 15% and thus to considerably improve the light sensitivity by keeping a similar cost compared to the previous CIS. The technology consists in a stacking of two separate chips using optimized processes: a pixel array circuit which uses a Back-Side Illuminated (BSI) technology, and a logic ISP circuit processed with a 65nm technology node. The two circuits are stacked with a wafer bonding process and connected together with copper TSVs.
The camera module, with dimensions of 8.5 x 7.8 x 5.7mm, is equipped with a 5-elements lens module and a VCM auto-focus actuator. The CIS is assembled in flip-chip on a ceramic substrate with a gold stud bumping process.
