Yole Developpement publishes an interview with Peter Hark, Director of Automotive Sales and Marketing at Sunex. Few quotes:

"The low-end of [ADAS] market concerning rear view cameras is very mature and not very dynamic. The high-end is more about high resolution surround-view cameras from which images are stitched together to give a bird’s eye view of a car, i.e. for parking assist purposes. This area is enjoying high growth. Another growth area are forward-facing cameras which, due to new regulations (especially NCAP in Europe, but also in the U.S.), are being increasingly adopted.

At Sunex, we’ve developed what we call the NoGhost technology, which is able to reduce straylight effects. This has great value for HDR sensors. <...> Likewise thermally-compensated optics add value to computer vision applications such as forward sensing cameras where they can extend the operational temperature range."

Yole Developpement publishes 2015 Camera Module Industry Report. The Compact Camera Module (CCM) market is forecasted to double in the next five years.

"Driven by mobile and automotive applications, the CCM industry is expected to grow at a CAGR of 16.8% from 2014 - 2020, reaching a total aggregate revenue of US$51B by 2020.

Automotive module revenue reached $1.2B in 2014, and growing at a CAGR of 36% should reach $7.9B by 2020. This exceptional growth has mainly benefited the CCM industry’s second-tier players, but the response of market leaders will be worth watching.

There is a different market trajectory for the lens and sensor markets, which are now maturing at ~14% CAGR with the emergence of giant billion-dollar companies. The CCM and auto-focus manufacturing markets, which are still very fragmented and growing at ~20% CAGR, should experience consolidation over the next five years.

The current CCM industry is controlled by Asian firms, mainly Korean and Japanese, but we’re also witnessing the rise of Chinese firms and the restructure of Taiwanese firms. An ongoing price war has leveled the market, and most players have operations in China or Vietnam."

IEEE Transactions on Electron Devices opens an early access to ON Semi paper "A 47 Million Pixel High-Performance Interline CCD Image Sensor" by Shen Wang, Douglas A. Carpenter, Adam DeJager, James A. DiBella, James E. Doran, Robert P. Fabinski, Andrew Garland, James A. Johnson, and Ryan Yaniga. The 47MP CCD is said to be "the world’s highest resolution interline-transfer CCD, has been developed for industrial, machine vision, and aerial photography applications. The sensor features a 5.5-µm pixel, 16-output low-noise amplifier and a low-smear, fast-dump gate, horizontal lateral overflow drain, and on-chip temperature sensor. One challenge to manufacture this large sensor is stitching the sensor with different lithography tools, while still achieving equal or better image performance than its predecessor."


IEEE Journal on Solid-State Circuits publishes an open access paper "A Dynamic Vision Sensor With 1% Temporal Contrast Sensitivity and In-Pixel Asynchronous Delta Modulator for Event Encoding" by Yang, M., Liu, S.-C., and Delbruck, T., University of Zurich and ETH Zurich, Switzerland.

Adimec publishes "Top 5 predictions for the future in machine vision." Out of the top 5, two trends are related to image sensors:

• Trend #1 From CCD to CMOS even for high-end machine vision and defense systems.
• Trend #2 Smaller pixels for industrial image sensors.

"Today’s pixel sizes are 4.5 to 5.5 um (industrial cameras – much smaller in the consumer/ cell phone market). In 2-3 years, industrial sensors will have pixel sizes of 3 to 3.5 um. We anticipate this will be the end of the pixel size race. Now image sensor developers are able to focus on functionality such as improving the global shutter and performance."

Electronics Weekly: Consumer demand for connected home products, including wireless security cameras, dropped dramatically in the first half of 2015, according to Argus Insights. "Early adopters have gotten what they need, and now products are not compelling typical consumers to create a connected home."

"The big buzz last year was over security cameras. Dropcam was huge, and made even more news when it was acquired by Nest Labs, which had previously been acquired by Google. (The recent Nest camera has been more coolly received.) Kickstarter launches, such as the Canary and Piper security cameras attracted a lot of attention to the market, resulting in more new product introductions, but the optimism of 2014 turned into the reality of 2015 as that market has dropped, due partly to connectivity and usability issues."

As EF mentioned in comments to Stratio post, IR Laboratories acquired the assets of NoblePeak Vision Corp, the developer of TriWave Ge-enhanced CMOS SWIR FPA's, in 2010.

From the company's whitepaper:

"NoblePeak Vision has solved the problem of growing thick, pure defect free germanium on silicon with its TriWave® technology. Figure 2 shows schematically our growth technique which traps dislocations by exploiting their characteristic diagonal propagation. A single crystal seed emerges from the narrow aperture and serves as a crystalline template for a large defect-free island. The island is formed after silicon transistor formation. The conventional back-end of the CMOS process then proceeds as usual, with alternating layers of dielectric and metal used to interconnect transistors and to connect the germanium photodiode to the circuitry."


"Figure 3 shows a scanning electron micrograph (SEM) of one such island integrated into a 180 nm CMOS process with three levels of metal and a reflow micro lens used to increase fill factor. TriWave detectors of size from 2 um to 5.6 um and imaging arrays with pixels of size 7 um and 10 um have been fabricated in this technology."


"Figure 5 shows the measured spectral response compared to theoretical predictions for bulk germanium at 220K. The cut off is at longer wavelength than predicted, due to grown-in strain."


VGA Tri-Wave sensor:

• Package Cu W base, Covar lid, 26 pin, AR Sapphire window
• 21mm x 21mm x 13.5mm
• Hermetically sealed, Xenon backfilled
• 4-stage TEC provides cooling to -80 C in ambient temperatures up to +40C

Canon publishes a white paper on its recently announced C300 Mark II 4K Digital Cinema camera and a new Super 35mm sensor in its heart:

"Canon R&D never stops and a totally new generation CMOS Super 35mm image sensor is the heart of the stunning imagery of the C300 Mark II. Further innovations within the second generation proprietary photodiode design in combination with on-chip noise cancellation technology have simultaneously lowered the noise floor and elevated the saturation level of the charge well. In addition, a totally new microlens design heightens the efficiency of light direction onto the individual photodiodes – a combination that achieves a more than two-fold increase in effective sensor dynamic range. This provides a definitive 15-Stop dynamic range capability in this new cinematography camera.

The more controlled noise floor allows the ISO range to be extended up to ISO 102,400. The Luma signal to noise ratio is a superb 67dB over a range of ISO settings. In the original C300 image sensor there were two fast readout modes – one, at 1/60 sec progressive and another at 1/120 sec interlace. The new image sensor in the C300 Mark II has a single readout capability of up to 1/120 sec progressive – further reducing rolling shutter skew effects."


"The C300 Mark II has a significant extension of dynamic range to 15-Stops – offering impressive HDR imaging capabilities – and the linear light digital representation for each of the 2K / HD video components is at a high 14-bit depth. This, in turn, allows for a far more favorable disposition of digital codes when mapping the nonlinear Opto Electronic Transfer Function (OETF) – a logarithmic curve termed Canon Log2.

An important extension was made to the Canon Log2 curve above the peak white level (the maximum level that can be delivered by the image sensor) – this being a 2-Stop continuation of the transfer function that is intended to support possible “push-pull” image manipulation in the color grading process."

Digitimes: Sony is to ramp up its image sensor production capacity by 31% in 2016, and plans focusing on mid-range and entry-level phone models, according to Digitimes Research. Sony also plans to triple its lens module shipments during the period from 2014-2017, Digitimes Research says.

Samsung Electronics has not used in-house developed image sensor products on its flagship models for over one-and-a-half years, not even in the recently released Galaxy Note 5, which comes with a Sony IMX240 sensor.

Samsung's adoption of Sony's CIS sensors may affect confidence of other first-tier smartphone brands in Samsung's image sensor products, which in return is likely to force the Korea company's CIS business unit to cooperate with second-tier handset brands. This is said to have an unfavorable impact on other image sensor makers, including Ominivision, ON Semi and those in Taiwan.

Korea Times: SK Hynix has invested 2.2 billion won (~ $1.86M) in Stratio, a Silicon Valley startup, in what officials say is a part of a corporate strategy to increase its stake in the rising image sensor segment. For that amount, SK Hynix got a 9.1% stake in Stratio. Other Stratio investors include K Cube Ventures (Tech for Korea), a venture company that funds and supports startups and young entrepreneurs in Korea, that invested $1M in October 2014.

Stratio develops Ge-on-Si based SWIR image sensors, said to be cheaper than their predecessors. The company has been established in 2013 and led by Lee Jae-hyung, who worked at Boston Consulting Group and Samsung Electronics. Stratio Photonics West 2015 presentation sheds some light on its technology and value proposition:


Semicon West startup introduction page states: "Stratio, Inc. was founded in 2013 by four Stanford Electrical Engineering PhDs. Stratio’s core technology is low-cost germanium (Ge) based short wavelength infrared (SWIR) image sensors suitable for incorporation with mobile devices. Stratio’s sensor utilizes a proprietary hybrid process that combines selective Ge epitaxial growth with established Si CMOS technology to overcome the limitations of conventional InGaAs-based SWIR sensors. Stratio's unique manufacturing process has a high thermal budget and results in a two chip package (sensor and ROIC) that allows for greater manufacturing flexibility than traditional monolithic sensor solutions. In addition, Stratio is developing a low-cost, portable hyperspectral imaging system for use with our sensor."


Stratio's Youtube video from May 2014 shows its SWIR camera attachment for iPhone:
