BusinessWire: Korean SOS Lab (Smart Optical Sensors Lab) has raised $6m for its automotive LiDAR. The lead investor in this series A round is Mando, a top-tier automotive supplier.

BusinessWire: In spite of rumors about technological troubles, Quanergy announces its Series C funding at a valuation exceeding $2 billion, with an un-named global top-tier fund as the lead investor. The Series C financing is sad to take the company well beyond its planning horizons to cash-flow and operating breakeven, and keeps the company’s IPO process on track.

"Demand for Quanergy’s solutions continues to be strong, with revenue increasing rapidly and bookings exceeding forecast. Product and software development continues at a brisk pace. Substantial orders for the company’s S3 solid-state sensor were fulfilled this year. Rapid innovation continues to increase the field of view (FoV) and range for the S3 in outdoor environments.

Since the end of 2017, Quanergy has had an annual production capacity of one million solid-state sensors at its fully automated production line in Silicon Valley. The completion of this round of financing will further enhance the company's capital reserve, to accelerate innovation and commercialization of its hardware, software and smart sensing solutions, and construction of ultra-large-scale production facilities.

"With our advanced technology, we have reduced the price of solid-state LiDAR to a few hundred dollars in volume,” said Louay Eldada, CEO of Quanergy. “Our third-generation solid-state LiDAR is being developed to fully integrate the sensor on a single chip. For Quanergy, the most important focus at the moment is to speed up the production ramping and prove our strength with mass-produced products."

PRNewswire: Israeli Guardian Optical Technologies announces an additional investment of $2.5m. The new investment is part of a pre-B round that totals $5.6M that will be used to expand the R&D team to serve the companies' expanding customer base as well as supporting customers' projects.

Guardian Optical sensor empowers car manufacturers to build safer cars, and at a lower cost, by eliminating the need to install multiple sensors throughout the car. Patent-pending sensor technology provides real-time, information on occupancy status based on three interconnected layers of information: video image recognition (2D), depth mapping (3D), and micro- to macro-motion detection. The sensor detects the location and physical dimensions of each occupant and can identify the difference between a person and an inanimate object.

Sensation Cooperation Project in Europe

SENSATION, a project within the EUREKA PENTA Cluster managed by AENEAS Industry Association, is developing innovative image capture, transmission and processing technologies for high-end Machine Vision and Broadcast applications. The project focuses on key requirements common to all professional vision-based applications namely: higher spatial resolution, higher frame rate, wider colour gamut, higher DR and improved image quality.

Machine vision calls for small pixel, high resolution sensors that can perform high quality inspection at high speeds. In the broadcast market, demand is being driven by the migration from HDTV to UHDTV. The UHDTV standard supports 4K and 8K resolutions, 12 bits per pixel (compared to 10 bits in HDTV), a wider colour gamut and an increased DR.

The SENSATION project brings together key European players in the imaging industry including R&D institutes specialized in image sensor technologies, image sensor designs and video processing; fabless design houses; a semiconductor manufacturer; image compression experts and system integrators. Through this collaboration the partners can strengthen Europe’s ability to compete in global markets for image capture, processing and transmission.

The partners will cooperate on the development of the following:
  • Development of (building blocks for) CMOS image sensors: smaller global shutter pixels, increased dynamic range, increased data rates, auto-focus pixels, improved ADC’s, ultra-high-speed architectures and high speed serial interfaces
  • New solutions for camera transmission
  • Demonstration of results in cameras for Machine Vision and Broadcast, and demonstration of separate image sensor evaluation set-ups
  • Standards for a high-speed serial interface for image sensors, image compression and camera interfaces.

Image sensor papers have a strong appearance in IEDM 2018 Program:

1.5µm dual conversion gain, backside illuminated image sensor using stacked pixel level connections with 13ke- full-well capacitance and 0.8e- noise
V. C. Venezia, A. C-W Hsiung, K. Ai, X. Zhao, Zhiqiang Lin, Duli Mao, Armin Yazdani, Eric A. G. Webster, L. A. Grant, OmniVision Technologies
A 1.5µm pixel size, 8 mega pixel density, dual conversion gain (DCG), back side illuminated CMOS image sensor (CIS) is described having a linear full-well capacity (FWC) of 13ke- and total noise of 0.8e- RMS at 8x gain. The sensor adopts a world smallest 1.5µm pitch, stacked pixel-level connection (SPLC) technology with greater than 8M connections, maximizing fill-factor of the photodiode and dimensions of the associated transistor dimensions to achieve a large FWC and low noise performance at the same time. In addition, by allocating transistors into two different layers, the DCG function can be realized with 1.5µm pixel size.

A. Tournier, F. Roy, Y. Cazaux*, F. Lalanne, P. Malinge, M. Mcdonald, G. Monnot**, N. Roux**, STMicroelectronics, **CEA Leti, **STMicroelectronics
We developed a High Dynamic Range (HDR) Global Shutter (GS) pixel for automotive applications working in the charge domain with dual high-density storage node using Capacitive Deep Trench Isolation (CDTI). With a pixel size of 3.2µm, this is the smallest reported GS pixel achieving linear dynamic range of 98dB with a noise floor of 2.8e-. The pinned memory isolated by CDTI can store 2 x 8000e- with dark current lower than 5e-/s at 60°C. A shutter efficiency of 99.97% at 505nm and a Modulation Transfer Function (MTF) at 940nm better than 0.5 at Nyquist frequency is also reported.

High Performance 2.5um Global Shutter Pixel with New Designed Light-Pipe Structure
T. Yokoyama, M. Tsutsui,Y. Nishi, I. Mizuno, V. Dmitry, A. Lahav TowerJazz
We developed a 2.5um global shutter (GS) CMOS image sensor pixel using an advanced Light-Pipe (LP) structure designed with novel guidelines. To the best of our knowledge, it is the smallest reported GS pixel in the world. The developed pixel shows an excellent Quantum Efficiency (QE), Angular Responses (AR) and very low Parasitic Light Sensitivity (PLS). Also, even in oblique light condition of 10 degrees, the 1/PLS is maintained to about half value. These key characteristics allow development of ultra-high resolution sensors, industrial cameras with wide aperture lenses and low form factors optical modules for GS mobile applications.

Back-Illuminated 2.74 µm-Pixel-Pitch Global Shutter CMOS Image Sensor with Charge-Domain Memory Achieving 10k e- Saturation Signal
Y. Kumagai, R. Yoshita, N. Osawa, H. Ikeda, K.Yamashita, T. Abe, S. Kudo, J. Yamane, T. Idekoba, S. Noudo, Y. Ono, S.Kunitake, M. Sato, N. Sato, T. Enomoto, K. Nakazawa, H. Mori, Y. Tateshita, and K. Ohno, Sony Semiconductor
A 3208×2184 global shutter image sensor with back-illuminated architecture is implemented in a 90 nm/65 nm imaging process. The sensor, having 2.74 µm-pitch-pixels, achieves 10000 electrons full-well capacity and -80 dB parasitic light sensitivity. Furthermore, 13.8 e-/s dark current at 60°C and 1.85 erms random noise are obtained. In this paper, the structure of a pixel with memory along with saturation enhancement technology is described.

A CMOS Proximity Capacitance Image Sensor with 16µm Pixel Pitch, 0.1aF Detection Accuracy and 60 Frames Per Second
M. Yamamoto, R. Kuroda, M. Suzuki, T. Goto, H. Hamori*, S. Murakami*, T. Yasuda*, and S. Sugawa, Tohoku University, *OHT Inc.
A 16µm pixel pitch 60 frames per second CMOS proximity capacitance image sensor fabricated by a 0.18µm CMOS process technology is presented. By the introduction of noise cancelling operation, both fixed pattern noise and kTC noise are significantly reduced, resulting in the 0.1aF detection accuracy. Proximity capacitance imaging results using the developed sensor are also demonstrated.

Through-silicon-trench in back-side-illuminated CMOS image sensors for the improvement of gate oxide long term performance
A. Vici, F. Russo*, N. Lovisi*, L. Latessa*, A. Marchioni*, A. Casella*, F. Irrera, Sapienza University of Rome, *LFoundry, a SMIC Company
To improve the gate oxide long term performance of MOSFETs in back side illuminated CMOS image sensors the wafer back is patterned with suitable through-silicon-trenches. We demonstrate that the reliability improvement is due to the annealing of the gate oxide border traps thanks to passivating chemical species carried by trenches.

High-Performance Germanium-on-Silicon Lock-in Pixels for Indirect Time-of-Flight Applications
N. Na, S.-L. Cheng, H.-D. Liu, M.-J. Yang, C.-Y. Chen, H.-W. Chen, Y.-T. Chou, C.-T. Lin, W.-H. Liu, C.-F. Liang, C.-L. Chen, S.-W. Chu, B.-J. Chen, Y.-F. Lyu, and S.-L. Chen, Artilux Inc.
We investigate and demonstrate the first Ge-on-Si lock-in pixels for indirect time-of-flight measurements. Compared to conventional Si lock-in pixels, such novel Ge-on-Si lock-in pixels simultaneously maintain a high quantum efficiency and a high demodulation contrast at a higher operation frequency, which enable consistently superior depth accuracies for both indoor and outdoor scenarios. System performances are evaluated, and pixel quantum efficiencies are measured to be more than 85% and more than 46% at 940nm and 1550nm wavelengths, respectively, along with demodulation contrasts measured to be higher than 0.81 at 300MHz. Our work may open up new routes to high-performance indirect time-of-flight sensors and imagers, as well as potential adoptions of eye-safe lasers (e.g. wavelengths longer than 1.4µm) for consumer electronics and photonics.

CMOS-Integrated Single-Photon-Counting X-Ray Detector using an Amorphous-Selenium Photoconductor with 11×11-µm2 Pixels
A. Camlica, A. El-Falou, R. Mohammadi, P. M. Levine, and K. S. Karim, University of Waterloo
We report, for the first time, results from a single-photon-counting X-ray detector monolithically integrated with an amorphous semiconductor. Our prototype detector combines amorphous selenium (a-Se), a well known X-ray photoconductive material suitable for large-area applications, with a 0.18-µm-CMOS readout integrated circuit containing two 26×196 photon counting pixel arrays. The detector features 11×11-um2 pixels to overcome a-Se count-rate limitations by unipolar charge sensing of the faster charge carriers (holes) via a unique pixel geometry that leverages the small pixel effect for the first time in an amorphous semiconductor. Measured results from a mono-energetic radioactive source are presented and demonstrate the untapped potential of using amorphous semiconductors for high-spatial-resolution photon-counting Xray imaging applications.

High Performance 2D Perovskite/Graphene Optical Synapses as Artificial Eyes
H. Tian, X. Wang, F. Wu, Y. Yang, T.-L. Ren, Tsinghua University
Conventional von Neumann architectures feature large power consumptions due to memory wall. Partial distributed architecture using synapses and neurons can reduce the power. However, there is still data bus between image sensor and synapses/neurons, which indicates plenty room to further lower the power consumptions. Here, a novel concept of all distributed architecture using optical synapse has been proposed. An ultrasensitive artificial optical synapse based on a graphene/2D perovskite heterostructure shows very high photo-responsivity up to 730 A/W and high stability up to 74 days. Moreover, our optical synapses has unique reconfigurable light-evoked excitatory/inhibitory functions, which is the key to enable image recognition. The demonstration of an optical synapse array for direct pattern recognition shows an accuracy as high as 80%. Our results shed light on new types of neuromorphic vision applications, such as artificial eyes.

Hybrid bonding for 3D stacked image sensors: impact of pitch shrinkage on interconnect robustness
J. Jourdon,, S. Lhostis, S. Moreau**, J. Chossat, M. Arnoux***, C. Sart, Y. Henrion, P. Lamontagne, L. Arnaud**, N. Bresson**, V. Balan**, C. Euvrard**, Y. Exbrayat**, D. Scevola, E. Deloffre, S. Mermoz, A. Martin***, H. Bilgen, F. Andre, C. Charles, D. Bouchu**, A. Farcy, S. Guillaumet, A. Jouve**, H. Fremont*, and S. Cheramy**, STMicroelectronics, *University of Bordeaux, **CEA-LETI, ***STMicroelectronics
We present the first 3D-stacked CMOS Image Sensor with a bonding pitch of 1.44 µm. The influence of the hybrid bonding pitch shrinkage (8.8 to 1.44 µm) from the process point of view to a functional device via the robustness aspect is studied. Smaller bonding pads do not lead to any specific failure.

Few other papers that are not directly related to imaging, but might become more relevant some day:

M.J.W. Rodwell, Y. Fang, J. Rode, J. Wu, B. Markman, S. T. Suran Brunelli, J. Klamkin, M Urteaga*, University of California, Santa Barbara, *Teledyne Scientific Company
We examine potential 100-340 GHz wireless applications in communications and imaging, and examine the prospects of developing the mm-wave transistors needed to support these applications.

High Voltage Generation Using Deep Trench Isolated Photodiodes in a Back Side Illuminated Process
F. Kaklin, J. M. Raynor*, R. K. Henderson, The University of Edinburgh, *STMicroelectronics Imaging Division
We demonstrate passive high voltage generation using photodiodes biased in the photovoltaic region of operation. The photodiodes are integrated in a 90nm back side illuminated (BSI) deep trench isolation (DTI) capable imaging process technology. Four equal area, DTI separated arrays of photodiodes are implemented on a single die and connected using on-chip transmission gates (TG). The TGs control interconnects between the four arrays, connecting them in series or in parallel. A series configuration successfully generates an open-circuit voltage of 1.98V at 1klux. The full array generates 423nW/mm2 at 1klux of white LED illumination in series mode and 425nW/mm2 in parallel mode. Peak conversion efficiency is estimated at 16.1%, at 5.7klux white LED illumination.

Error-Resilient Analog Image Storage and Compression with Analog-Valued RRAM Arrays: An Adaptive Joint Source-Channel Coding Approach
X. Zheng, R. Zarcone*, D. Paiton*, J. Sohn, W. Wan, B. Olshausen* and H. -S. Philip Wong, Stanford University, *University of California, Berkeley
We demonstrate by experiment an image storage and compression task by directly storing analog image data onto an analog-valued RRAM array. A joint source-channel coding algorithm is developed with a neural network to encode and retrieve natural images. The encoder and decoder adapt jointly to the statistics of the images and the statistics of the RRAM array in order to minimize distortion. This adaptive joint source-channel coding method is resilient to RRAM array non-idealities such as cycle-to-cycle and device-to-device variations, time-dependent variability, and non-functional storage cells, while achieving a reasonable reconstruction performance of ~ 20 dB using only 0.1 devices/pixel for the analog image.

Event-Based Vision to Dominate MV Applications? publishes Prophesee article with bold predictions for the machine vision future:

"Event-based vision is poised to take over from the frame-based approach used by traditional film, digital and mobile phone cameras in many machine-vision applications. The mode of operation of state-of-the-art image sensors is useful for exactly one thing: photography, i.e. for taking an image of a still scene.

An ´ideal´ image sensor samples parts of the scene that contain fast motion and changes at high sampling rates and slow changing parts at slow rates, all at the same time – with the sampling rate going to zero if nothing changes. Obviously, this will not work using one common single sampling rate, the frame rate, for all pixels of a sensor. Conversely, one wants to have as many sampling rates as there are pixel in the sensor – and let each pixel’s sampling rate adapt to the part of the scene it sees.

Melexis Announces 2nd Generation ToF Sensor

Melexis announces "a major upgrade to ToF technology for the automotive industry, its next-generation QVGA ToF sensor chipset and a forthcoming VGA ToF sensor."

The new ToF sensors are AEC-Q100 qualified and suitable for automotive applications including gesture recognition, driver monitoring and people/object detection. The new MLX75024 ToF QVGA sensor doubles the sensitivity of the previous generation while maintaining the same resolution and ambient light robustness. This allows it to operate in lower light levels or reduce the illumination power required by at least 30%. System efficiency is further enhanced by a 50% reduction in current consumption and the resulting lower heat generation allows the design of more compact cameras. A new selectable gain feature allows a trade-off between illumination power, accuracy and ambient light robustness. As a result of these, the SNR is two times better in low light conditions and distances greater than 1m. As an additional improvement, the sensor now integrates an on-chip temperature sensor, reducing system size and cost.

To support the latest MLX75024 QVGA ToF sensor, Melexis has developed the MLX75123BA ToF companion chip, which offers a three-fold improvement in front-end noise over its predecessor. The companion chip is used to configure parameters such as pixel gain, and now supports pixel binning to simplify hardware and software for lower resolution applications. Additionally, the MLX75123BA can support two MLX75024 sensors at the same time.

Melexis also has developed a new BSI VGA sensor. Initial sampling to automotive customers will start early 2019.
