8MP Stacked Sensor, 12MP Power and Speed Marvel and More From Sony

Sony Cx-News vol. 70 is entirely devoted to new and very impressive image sensor announcements. The first of the two most interesting ones is 1.55um BSI pixel-based IMX117CQT. This 1/2.3-inch 12.4MP sensor is an improvement on the similar but older IMX078CQK. The new sensor is faster, lower power, has wider light acceptance angle, and more:

The sensor is very fast delivering 35fps at full resolution at 430mW power. It also capable to 4K/60fps video (10b ADC mode) and includes HD-ish slow motion modes:

Another important announcement is the first stacked sensor product, the 1/4-inch 8MP 1.12um pixel ISX014, naturally, with integrated ISP:

Sony illustration of the stacked structure does not seem to have
any wafer-to-wafer contacts in the pixel array area

Not much information is given about the sensor. It supports 1940 x 1080p video at 30fps and 1280 x 720p video at 60fps. The built-in scalar function makes it possible to shrink all of the 8MP to perform 16:9 cropping for video. Power consumption is 270 mW in 8MP JPEG@15fps mode or 202 mW in 2MP YUV@30mode which are quite good numbers, possibly due to an advanced process node used for ISP die.

The image samples which were supposed to show the sensor's high quality, are of low resolution, unfortunately:

Another announcement is the new 1-inch 9.19MP CCDs: the ICX814ALG (B&W) and the ICX814AQG (color). The sensors have 4 outputs and multitude of readout modes, the fastest one being 1080p at 36fps:

Toshiba Announces 1.12um BSI Sensor with Improved SNR

PR Newswire: Toshiba announces a 13MP, 1.12um pixel sensor claimed to deliver high-image quality equivalent to a 1.4um pixel. The new T4K37 feature BSI and integrated color noise reduction (CNR) and fits into an 8.5mm x 8.5mm size camera module.

The miniaturization of pixel size impacts performance of light sensitivity and SNR in today's 1.12um pixel image sensors. BSI technology helps improve sensitivity, but is said to fall short on elevating image quality. Toshiba developed its newest image sensor with BSI and CNR integrated on the sensor to address both low-light sensitivity and SNR. As a result, the Toshiba CMOS image sensor provides approximately 1.5 times higher SNR than a 1.12um pixel sensor with no CNR.

Samples of the new Toshiba sensor, the T4K37, will be available in December 2012. Sample pricing begins at $20.00.

Update: It appears that Japanese PR has much more info. Among the pictures, it shows the CNR effect:

Here is the Google translation of CNR principle:

"CNR Our circuit has adopted the type to compare the image between frames by a digital filter circuit to suppress the color noise, without compromising a sense of resolution, of 1.12 micrometer pixel circuit not installed CNR SN ratio of about 1.5 times to accomplish, to achieve the SN ratio of the pixel corresponding to 1.4 micrometers."

The sensor is fast, it delivers 30fps at full 13MP resolution. The Japanese PR also has a table with two other sensors, apparently based on the same 1.12um pixel:

Update: Toshiba published a product page of the 1/3.07-inch T4K37 sensor. The block diagram shows a location of Color Noise Reduction part (CNR). The output format is either 8b or 10b.

ON Semi and Teledyne Designed 16MP MCT Sensor

Business Wire: ON Semiconductor collaborated with Teledyne Imaging Sensors to manufacture an Extremely Large Stitched Read Out Integrated Circuit (ELS ROIC) for astronomy.

The 16MP H4RG-15 consists of Teledyne’s HgCdTe detector material hybridized to a CMOS readout circuit. It is said to be the largest sensor ever produced for IR astronomy. The H4RG-15 63 mm x 63 mm stitched CMOS ROIC uses ON Semiconductor’s proprietary 180nm process. The ROIC is so large that only four die fit onto a 200 mm wafer.

The H4RG-15 ROICs were manufactured at ON Semiconductor’s fab located in Gresham, Oregon. With this project, ON Semiconductor has demonstrated that it can successfully produce the H4RG-15 with the yield required for this next generation sensor.

The H4RG-15 sensor has been installed at the University of Hawaii’s observatory on Mauna Kea to confirm the performance of the sensor under telescope observing conditions. "The resolution with which images can be captured using this new sensor system represents a major step forward in the progression of IR astronomy," said Dr. Donald Hall of the Institute for Astronomy at the University of Hawaii, who is the principal investigator for the NSF-funded H4RG-15 development program.

Pelican Imaging Capabilities Presented

Pelican Imaging starts to present its approach at different forums. Apparently, Mobiletrax' post is based on one of those presentations:

"The founders of Pelican Imaging started with the idea of using an array of low resolution photoplanes coupled to an array of small lenses and using the overlapping information to create astounding images and videos.

The core intellectual property (IP) starts by using an array of 16 inexpensive, mass produced accurately aligned cameras. The array creates 16 images – each one slightly different from the other since it is capturing the image from a slightly different angle. Because the input images all come from lenses and pixel technologies that are mature and low cost, the yield of the solution should be very good. You can see the 16 ‘similar’ images captured by using the 16 lenses in Figure 2.

"Because each image is taken from a slightly different angle, the processing logic can determine the distance objects are from the camera, thus providing a depth map of the scene... And, the 16 slightly different versions of the photo offer the ability for Pelican’s proprietary (and patent pending) software to synthesize a higher resolution image."

Some of the camera capabilities are shown in pictures:

Sony Issues Convertible Bonds to Fund Image Sensors Capacity Expansion

Benzinga: Sony announces that it is planning to issue a 150 billion yen ($1.9 billion) zero coupon convertible bond maturing in 2017. The 60 billion yen ($750 million) is slated for the expansion of Sony's CMOS sensor production facilities in Nagasaki (announced on June 22, 2012, with an expected total capital expenditure of approximately 80 billion yen, expected to be completed during the first half of the fiscal year ending March 31, 2014).

Tessera/DOC Cuts EDoF Development, Concentrates on MEMS Motors

Business Wire: Tessera announces its wholly owned subsidiary, DigitalOptics Corporation ("DOC") will focus its efforts on its core MEMS camera module business. DOC plans to reduce its workforce – not including those related to manufacturing operations in Zhuhai, China – by up to 40%.

As part of this process DOC plans to cease operations at its facility in Tel Aviv, Israel and to pursue a possible sale of, or other strategic alternatives for, its facility in Charlotte, North Carolina. These two facilities are not central to the MEMS camera module opportunity. Given full effect, the planned actions would reduce the non-Zhuhai workforce of 450 by approximately 180 employees.

DOC anticipates that the staff reductions and facility dispositions will be spread over the next two to three quarters to ensure continuity in the business as well as compliance with relevant legal requirements.

Tel Aviv facility was developing EDoF, OptiML Zoom, OptiML Low-Light and other computational optics technologies. It was based on two acquired startups - Eyesquad and Dblur, combined with few people left from Shellcase. A number of key people of this group left Tessera a year ago, in Aug. 2011.

"Camera module features and functions have increasing importance to consumers in the mobile phone market. The changes announced today will focus DOC on that market and are an important part of driving the business towards profitability," said Robert A. Young, president and CEO of Tessera.

Himax Reports CIS Sales Down, Wafer Optics Sales and Prospects Up

Himax reports its Q3 2012 results. The company CEO Jordan Wu updates on image sensor business status:

"In our CMOS image sensor product line, the delay of Win 8 launch from Q3 to Q4 affected our shipments of 1 mega-pixel sensor during the third quarter. However, we expect such demands to resume starting Q4 thanks to our design-wins with a number of tier-one laptop names. Beyond laptop, we have also won design-wins in smartphone, tablet and surveillance applications from a wide range of customers. We also launched a 5 mega-pixel sensor in the third quarter which targets smartphone market. It will begin some shipment in the fourth quarter.

Our wafer level optics experienced double digit growth during the third quarter. The production of WLO for VGA, or 300,000-pixel, lens in our fab has been made smoothly with high and stable yields. With that, we are moving up the scale to start sampling our WLO with HD, or 1 mega-pixel, resolution, which we believe has a good potential of taking up a meaningful amount of the front camera market for smartphone. We expect our HD WLO to start mass production in early next year.

Altasens Talks about Stacked Sensor Advantages

Altasens' patent application US20120267511 "Image sensor with hybrid heterostructure" by Lester Kozlowski has few interesting claims:

First, a stacked sensor structure is proposed:

The pixel array uses "optimized" pmos transistors. An example pixel capable of GS, S&H and CDS is shown on Fig. 6:

The main advantages of the stacked structure are (1) very good global shutter efficiency and (2) lower noise due to a special pmos transistor "optimization":

"FIGS. 7 and 8 [not shown here] compare the read noise achievable with optimized PMOS technology vs. standard CMOS technology wherein the source follower is formed in NMOS having flicker noise lower than readily achieved in common foundry processes, i.e., very good compared to what is readily available. Even so, the PMOS global shutter can yield a read noise of 1 e− (or holes) at a sense capacitance of 5 fF. The NMOS global shutter circuit instead has read noise of 3.5 e− at 5.5 fF. More importantly for long term development, the PMOS solution goes well below 1 e−0 as the sense capacitance is reduced while the NMOS solution plateaus well above 2 e−."
