Biometrics: fingerprint sensor products

Fingerprint sensors

Here are the fingerprint sensors that have at least existed once, excepted (simple) optical sensors.

Silicon manufacturers are fabricating these sensors.

Pionners

Here are some links related to pionner stories about making solid-state fingerprint sensors.

Teruhiko Tamori: with NEC, Sony, Sanyo (BMF)...

Opsis

(1994 Jul) Opsis SA offered a device using a conductive membrane deposited on a CMOS chip.
I'm still wondering if it is related to the Teruhiko Tamori R&D...

For the records, a (simplified) local copy of the Opsis website, years ago!

Fingerprint Cards

Fingerprint Cards is proposing RF modulation fingerprint sensors.

Foundry: SMIC, packaging: Amkor.

Partnership with Shenzhen O-Film Tech.

In 2012, Apple buys Authentec+Upek and stops the production. Validity has not yet a real offer, and Atmel stopped in 2008. Smartphone makers are becoming orphan, without fingerprint sensor providers: what a piece of luck! Fingerprint Cards took the opportunity...

Some specific partnerships with CrucialTec and Q-Tech, and the situation is not so clear. See further.

(2007 Sep) Backed by a new $5 million investment from L-1 Identity Solutions, Ultra-Scan is working to develop and make a new fingerprint reader that is much smaller than current scanners and is able to scan four fingers, instead of just one.

(2013 Mar) Qualcomm acquires Ultrascan.

Ultrascan has developped an ultrasound TFT device, 4 fingers as announced in 2007.

(2015 Mar) Qualcomm announces the launch of Qualcomm® Snapdragon Sense™ ID 3D Fingerprint Technology.

It seems there are two demos at the MWC2015: a regular sensor, and the same(?) below a glass, to demonstrate the ability of capturing fingerprint through the display glass. In the last case, the image is becoming very noisy (this is maybe the reason why there is the logos on screen?). 3D image, they said... check out Vkansee to compare. It seems that dry fingers are still a problem...

(2014 Apr): Chipworks tears down the Galaxy S5: confirms this is a Synaptics/Validity chip inside.

It seems that the metallic border of the button is used as a ground or signal line, likely useful for the sensor itself.

So there is the Validity chip on a flex -as usual-, but this time there are balls to go to the upper part of the button: it is likely that the conductive lines are directly done on the inside part of the button. I wonder about the number of "pixels", because the number of balls is pretty low, so likely a not so good resolution...

Let's call this chip the VAL004A8 :) Take care of the die mark, dated 2008, which is confusing...

Goodix

(2014 May) Goodix formerly known as Shenzhen Huiding Technology Co. Ltd. (a subsidiary of Mediatek, see also Elecvision), introduces a new active capacitance fingerprint sensor. Goodix presentation (OFweek).
By adopting a new original patented packaging technology, Goodix integrated the metal ring, sapphire cover and sensor into a small volume. The mode of operation is similar with Apple Touch ID technology. Products: GF6616, GF6626, GF6610 and GF6620. Minimum size is only 9.76mm x7.4mm x1.17mm.
Announced accuracy: FAR 1/50000 for a FRR 1/100 (at least, they give the FRR: Apple said nothing about that).

(2014 Sep) Goodix unveils their new generation of fingerprint identification solution - IFS (Invisible Fingerprint Sensor), developped with TPK which should enable to remove the ring, and use directly glass (450 to 700 microns thick).
300 microns sapphire protection (like the Apple 5S).

(2015 Jan) Goodix announces that their GF66X8 fingerprint sensor powers Meizu’s latest smartphone (the Meizu MX4).
Several parts exist, depending on the color/package:
{circle, square, rectangle}, {white, black}
Likely the same sensor behind. 96×96 pixels, maybe in 3 x (32x96), TBC.
You can find some more information at Chipworks (under the name GT6648, reverse of the Meizu phone).
