Imec Publishes Combined CCD-CMOS TDI Imager
Imec publishes flyer of Argus, a BSI TDI embedded CCD imager prototype featuring >90% QE and monolithic integration of a CCD module on CMOS for machine vision, remote sensing, life sciences, and scientific applications:

So explain why UV has its own line that goes all the way through the visible spectrum? Is this with a UV filter in place perhaps or a special UV version?
ReplyDeleteMaybe some special coating for UV-VIS conversion...
DeleteTim, there's 2 Image Sensor types available. In addition to the "Image Sensor" there is 'standard' additional circuitry and completely customized circuitry (not User customizable, you need to pay for the Die and order enough to make it worth the cost, so X million for the first 5000 and another million for 10x as many).
DeleteIn addition to the two "Sensor types" (and choice of Circuitry behind them) there is a choice of Filter in front of the Sensor's 4Kx256 Pixel Array.
You can choose the CCD to support FlexCIS, TDI, or High-speed.
The FlexCIS imager will be available in several versions. Filters integrated on top of the pixels can be customized for a specific spectral range targeting a specific application. There are monochrome, ultra-violet, near infrared, RGB (or similar) color filter and hyperspectral filter (HSI) versions will be available.
Assuming OTS your getting a B&W TDI that is the second Camera for a Cellphone (when there are two on one side).
Customized you could order some Pixels to be IR or UV sensitive for autofocus in a Consumer oriented Camera (regul ar point and shoot, not a specialty Camera).
You could also order a 'Leaking Gas Detector', it would simply include the necessary spectral gathering Filters and an Image Sensor behind that Array that is most sensitive to the spectrum resulting from that filtering.
The processing Stages behind the CCD, the CMOS Layers, could mathematically process the resulting Image and determine that the resulting spectral lines, at set proportions, constituted a specific Gas (and not just the surrounding Air).
The Chip would give a "No Alarm" vs. "Alarm" output (not a visible Image, a binary answer - one bit output). This would be very immune to false alarms, which is important with most Gas leaks.
This answer is probably long enough, did you need some more; there's my YouTube Channel - LowLightVideos .
So please tell me which fab can do this? Not Imec's for sure, since I know that very well.

ReplyDeleteYou can read their _limited_ .PDF for the aforementioned Sensor and .PDFs for their prior generation to see what's available now and in the pipe.
