In addition to moving some more of the circuitry from front to back they can add additional layers to enable PDAF and increase the Readout Speed.<br /><br />This Sensor is 'like' the Xperia XZ / Z Pro etc. (960 FPS Cellphone Sensor) except the DRAM is not as large (capable of such high speed) and the physical size is Full Frame (that's the "new" part, Full Frame).<br /><br />See: https://www.xda-developers.com/sony-imx378-comprehensive-breakdown-of-the-google-pixels-sensor-and-its-features/ and Mark Weir of Sony: https://youtu.be/oG2UPQfPNDs?list=PLWa6uO3ZUweB_LFvUpNPoxUs-9CtqFKN0 or even Wikipedia.Robhttps://www.blogger.com/profile/08222535289392471857noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-26473293040231864442017-04-23T09:22:20.036+03:002017-04-23T09:22:20.036+03:00I am not 100 % sure if you are right.

The ISSCC paper had 3 layers of silicon and in this Sony presentation I do see only 2 layers. But the device in this presentation is a very large one, so the large supporting chip can easily have memory and processing on-board without the need for an extra layer with DRAM. So after all, this presentation still may have the same functionality as the ISSCC paper, but only with two layers of silicon and not three. <br />If someone has another opinion .... ???Albert Theuwissen - Harvest Imagingnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-5536881355601662122017-04-20T17:28:58.284+03:002017-04-20T17:28:58.284+03:00Is this the same stack technology as the ISSCC pap...Is this the same stack technology as the ISSCC paper in Feb, in the Experia XZ Motioneye camera?Dick Jamesnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-84123231580487686882017-04-20T15:13:40.199+03:002017-04-20T15:13:40.199+03:00Right.
