Xiaomi 17 has adopted 'LOFIC' bragging rights in its marketing CIS x Leica material, so this is now rather 'meh' ?

It's different. when you read an analog GS sensor, you have two exposures: one is GS and the other is RS. so you can have a lot of artefacts due their mixture. But in in-pixel ADC, these 2 rxposures are both GS, so the FD leakage adds a small extra-exposure time but will not generate artefacts.

I think it resolves a fraction of problems in a long computation chain. that is why it cannot find real applications after so much ressource invested inside.

Yes of course. What's the ASP? I was referring to the cameras on the back where the value is. Customers look at the pictures, not at the camera behind FaceID or any other proximity sensors.

Finally iPhone image sensors will be US made, after many billions of sensors sold. It took politics to enable or force the economics.

Well, Samsung was kind of forced to invest heavily invested in the Texas fab to avoid Trump Tariffs.
And btw, Sony is also sourcing CIS from TSMC fab in Taiwan.

Sony was never the sole supplier. There is a STMicro sensor for FaceID.

2026-02-06T02:29:15.906+02:00

Apple has sourced GS sensors for their FaceID for years. So Sony hasn't been the sole source anyway. That Apple works with Samsung has also spread for a while. Trump has pushed Apple to pull their supply chain into the US for a while now, but mostly Apple seemed to have done final assembly and not chip manufacturing in the US. So to me the fact that Samsung now produces state-of-the-art mobile grade sensors in the US is big news and thus this post is spot-on.

This is not an accurate statement: "The CIS is made with wafer-to-wafer hybrid bonding ... requires precise process control and only Sony and Samsung have commercialized it."

2026-02-05T10:28:09.997+02:00

I am sorry what has this to do with tariffs? Apple has historically sourced from Sony only which manufacture 100% in Japan. It was also one of the few cases of single supplier. The news should be that Sony is no longer the single supplier for Apple.

This was published in VLSI 2025. Fig. 6 of that paper showed about 156dB. In top image here, the brightest spot of the light bulb corresponds to roughly 10M photon counts (140dB).

2026-02-03T16:50:58.694+02:00

How does the image prove that the sensor has 156dB? I see nothing but flare at low photon range. It looks like the scene is maybe 100db? If so, what is the point of having incredibly high dynamic range sensors. The optical system can't catch up.

"The earlier the arrival of the first incident photon, the brighter the incident light." Well, not really true, but on the average true.

I wonder how Canon's 5.94um pixel-level photon-counting image sensor comparing to Sony's 6.39um pixel-ADC global shutter image sensor.

2026-02-01T19:50:42.405+02:00

Let's see if the the issue is a lack of experience of the CEO or if the technology is too disruptive and coming to market too early. The powerful players are those who already made some parternship and/or jda's and took the information they need.
Current sensors are already obsolete, time for innovating further with high caliber people (not with the current VP sensor) and be very careful on protecting the IP's like stmicro is doing, you shall see dramatic changes.

2026-02-01T15:47:52.867+02:00

Valid point! I would like to challenge the "immediately" here though: the conversion time for digital pixel sensor (pixel ADCs) is in the order of milliseconds (~1ms in this paper), as opposed to micro seconds of conventional column readout. Signal and reset stay on FD all that time until the ADC has finished the conversion. Hence my question above about potential issues of this long storage on FD. Also, since CDS time is so long, how does this affect 1/f and RTS noise of the source follower?

2026-02-01T11:25:05.931+02:00

This is a digital pixel sensor in which the pixel information is immediately converted and stored in the digital domain. In this way FD leakage and parasitic light sensitivity are no issues.

2026-01-31T15:28:37.782+02:00

I am wandering if FD leakage and parasitic light sensitivity are a problem in some applications and how/if they are solved in this work. Since signal has to be stored for a full frame time on FD, how is parasitic light on FD affecting a pixel which converts early (dark) and one which converts late ( bright)?
