Samsung Announces 1.4um FSI Based Imagers

Business Wire: Samsung announced 5MP S5K4E2 and 3MP S5K5CA imagers, both based on 1.4um pixel, apparently FSI. S5K4E2 pixel is said to use SEES (Samsung Enhanced Energy Steering) technology. "The SEES pixel, integrates more light into an optimized pixel structure to present clear, high resolution images." No such claim presented for S5K5CA pixel. The 1/4-inch 5MP S5K4E2 imager integrated EDoF IP with in-focus range from 15cm to infinity and delivers full resolution video at 15fps speed. It's designed to fit into a 6.5mm x 6.5mm module with a height of 4.5mm. The sensor has "advanced noise removal logic" integrated.

S5K5CA is a 1/5-inch, 3MP imager SoC that with integrated ISP, fitting into 6.5mm x 6.5mm fixed focus camera module. The S5K5CA is said to offers 10 percent improvement in SNR against the previous 3MP imaging solution, apparently based on 1.75um pixel.

Samsung’s new S5K4E2 is currently sampling and will be in mass production by the end of Q1 2010. Samsung’s S5K5CA is in volume production for many of the world’s top handset manufacturers today with products on the market expected later in 2010.

  1. I assume the EDoF technology comes from Tessera

  2. Must not be very proud of the sensitivity. No specs.

  3. If a 1.4u FSI pixel can produce a 4.5mm module height on a 5 mp sensor, what mdule height can the omnivision 1.1u BSI pixel produce for a 1/5" or 1/6" sensor?

  4. i heard the ov 1.1um bsi pixel has sensitivity similar to the 1.4um bsi pixel, 670mv/lux-sec which is not that great.

    also, in addition to samsung having exposure to tessera's edof from eyesquad, samsung may also have been able to take advantage of dxo's edof the ip to which tessera recently acquired. additionally, i believe transchip which was acquired by samsung in 2007 was also working on edof at the time of the acquisition.

    i am looking forward to seeing samsung's bsi product made from bulk wafers for phones as well as aptina's 1.1um bsi product in the fall.

  5. @ dxo's edof the ip to which tessera recently acquired.

    Tessera acquired Dblur and Eyesquad EDoFs, rather than DxO one. DxO is rumored to be for sale as well, but as far as I know, it's not acquired yet.

    @ transchip which was acquired by samsung in 2007 was also working on edof at the time of the acquisition.

    To the best of my knowledge, Transchip had no its own EDoF at the time of acquisition.
