Paper on QE Improvement with Surface Textures

Image Sensors World        Go to the original article...

Huazhong University of Science and Technology, Wuhan, China, publishes an AIP paper "Photon management with superlattice for image sensor pixels" by  Yuqing Cao,  Zijian Zhang, and Ken Xingze Wang.

"It is important to increase light absorption and quantum efficiency in image sensor pixels, especially for wavelength ranges in which material absorption is weak. Surface textures, including nanostructure lattices, have been invented for significant improvement in light absorption. Those nanostructures typically support a number of physical processes for which the optimal geometries are different. We design a class of nanostructure superlattices to enable the co-optimization of different physical processes for further enhancement in light absorption."

3rd Order Sigma-Delta ADC for Image Sensor

Image Sensors World        Go to the original article...

AMS and Madeira University, Portugal, publish an MDPI paper "Design Improvements on Fast, High-Order, Incremental Sigma-Delta ADCs for Low-Noise Stacked CMOS Image Sensors" by Luis Miguel Carvalho Freitas and Fernando Morgado-Dias.

"It is known that thermal and flicker noise sources are the main contributors to the degradation of the sensor performance, concerning the sensor output image noise. This paper presents an indirect way to reduce both the thermal and the flicker noise contributions by using thin-oxide low voltage supply column readout circuits and fast 3rd order incremental sigma-delta converters with noise shaping capabilities (to provide low noise output digital samples—74 μVrms; 0.7 e−rms; at 105 μV/e−), and thus performing correlated double sampling in a short time (19 μs), while dissipating significant low power (346 μW). Throughout the extensive parametric transistor-level simulations, the readout path produced 1.2% non-linearity, with a competitive saturation capacity (6.5 ke−) pixel. In addition, this paper addresses the readout parallelism as the main point of interest, decoupling resolution from the image noise and the frame rate, at virtually any array resolution."

OSA Optics Express publishes a paper "Broadband responsivity enhancement of Si photodiodes by a plasmonic antireflection bilayer" by Jongcheol Park, Il-Suk Kang, Gapseop Sim, Tae Hyun Kim, and Jong-Kwon Lee from National NanoFab Center and Cheongju University, Korea.

"Randomly distributed plasmonic Ag nanoparticles (NPs) with various sizes were fabricated by a reflow process to an island-shaped Ag thin-film deposited on a Si photodiode. These NPs conformally enclosed by an antireflective (AR)-type SiNx/SiO2 bilayer reveal significantly diminished reflectance in a broad wavelength (500 nm - 1100 nm) as compared to the cases of Ag NPs or SiO2 layer enclosing Ag NPs on the Si substrate. Accordingly, the forward scattering and the total reflection along with wide-angle interference in between the dielectric bilayer incorporating the Ag NPs induce highly increased light absorption in the Si substrate. The fabricated Si photodiode adopting the plasmonic AR bilayer shows the responsivity peak value of 0.72 A/W at 835 nm wavelength and significant responsivity enhancement up to 40% relative to a bare Si photodiode in a wavelength range of 500 nm to 1000 nm."

Yole CIS Market Report: Smaller Companies Expand Market Share

Image Sensors World        Go to the original article...

Yole Developpement publishes an update of its "Status of CMOS Image Sensor Industry 2021 report."  Pierre Cambou, Principal Analyst, reports interesting observations:

"For CIS players, 2020 did not play out similarly to 2019, in fact it was almost the opposite, with the smaller players doing best. Sony didn’t grow, but Samsung grew 13%, OmniVision, Smartsens and SK Hynix grew about 30%, while Galaxycore grew 52% YoY.

The CIS industry output stayed close to its structural limit all through the year, and especially in Q3-2020. For the full year, the whole industry grew by 7.3% YoY in revenue, in line with Yole’s expectation.

Until 2019 mobile device cameras were the main growth contributor to the CIS market. But in 2020 this is no longer the case. Computing, automotive and security market applications have now outpaced the growth of mobile device.
"

The US$20.7 billion CIS industry is still heavily dominated by mobile and consumer applications, representing more than 72% of revenues. Yet, despite all headwinds in 2020, computing, automotive and security have each grown to similar shares, reaching about 8% of CIS revenues, and 23% combined. They had represented 21% in 2019.

Tower Overviews Optical Fingerprint Technologies

Image Sensors World        Go to the original article...

Amos Fenigstein, Managing Director of CIS R&D at Tower, publishes a nice review article "Image Sensors: Leaving Fingerprints Everywhere in the Age of Consumer Data Protection and Security." Few quotes:

There are two major “under screen” optical sensors technologies:
  • a lens-type sensor that uses a system lens and thus uses pixels the size of 5 to 6 microns to resolve the 50um features resolution in the fingerprint, 
  • a 1:1 sensor that does not use a lens and thus, requires large pixels, of around 50um.
The lens-type sensor, if used under LCD, requires an internal light source at the near Infrared regium as the LCD screen is not transparent to visible light. However, if used under OLED, the OLED screen itself acts as the light source and thus, the pixels are required to be sensitive to visible light. This is true for both lens-type sensors and 1:1 sensors under OLED screen (1:1 sensors are not being used under LCD).
The reason to use 1:1 sensors, although it is much larger than a lens-type and as a result are much more costly, is the minimum sensor height that can be achieved only with a lens-less sensor. Such small heights, as small as half a millimeter, is crucial for high end 5G smartphones, where there is only 0.6mm space between the battery on the back and the screen.

Graphene Pixel Experiments

Taiwan National Tsing Hua University publishes a paper "A Graphene/Polycrystalline Silicon Photodiode and Its Integration in a Photodiode–Oxide–Semiconductor Field Effect Transistor" by Yu-Yang Tsai, Chun-Yu Kuo, Bo-Chang Li, Po-Wen Chiu, and Klaus Y. J. Hsu.

"The present work reports the observation of the electrical and optoelectronic characteristics of a graphene/polycrystalline silicon junction and explores one possible usage of the junction. The current–voltage curve of the junction was measured to show the typical exponential behavior that can be seen in a forward biased diode, and the photovoltage of the junction showed a logarithmic dependence on light intensity. A new phototransistor named the “photodiode–oxide–semiconductor field effect transistor (PDOSFET)” was further proposed and verified in this work. In the PDOSFET, a graphene/polycrystalline silicon photodiode was directly merged on top of the gate oxide of a conventional metal–oxide–semiconductor field effect transistor (MOSFET). The magnitude of the channel current of this phototransistor showed a logarithmic dependence on the illumination level. It is shown in this work that the PDOSFET facilitates a better pixel design in a complementary metal–oxide–semiconductor (CMOS) image sensor, especially beneficial for high dynamic range (HDR) image detection."
