Chipworks reverse engineered the new Sony-Ericsson SE006 phone and revealed that its 16MP BSI sensor is based on 1.12um pixels. Chipworks writes:
"Sony is again first to market – this time with a next generation 1.1 µm class pixel. Sony announced the IMX081PQ Exmor-R CMOS image sensor and IU081F camera module in October 2010. Featuring 1.12 µm pixels, the camera modules are claimed to be the smallest and thinnest modules of this resolution for mobile phones. These devices mark Sony’s first deployment of Exmor-R (back illuminated) sensors in mobile applications, and are part of Sony’s strategy to aggressively pursue design wins in high-end mobile phones.
The 10.5 mm x 10.5 mm x 7.9 mm module features a chip-on-board (COB) mounted image sensor, an autofocus mechanism, and a printed wiring board (PWB) with embedded components – something which Sony has been a bit of a laggard on until now. The IMX081PQ uses Bayer patterned color filters and microlenses on a 1.1 µm pitch."
