dToF Sensor with In-pixel Processing

Image Sensors World        Go to the original article...

In a recent preprint ( Gyongy et al. describe a new 64x32 SPAD-based direct time-of-flight sensor with in-pixel histogramming and processing capability.

3D flash LIDAR is an alternative to the traditional scanning LIDAR systems, promising precise depth imaging in a compact form factor, and free of moving parts, for applications such as self-driving cars, robotics and augmented reality (AR). Typically implemented using single-photon, direct time-of-flight (dToF) receivers in image sensor format, the operation of the devices can be hindered by the large number of photon events needing to be processed and compressed in outdoor scenarios, limiting frame rates and scalability to larger arrays. We here present a 64 × 32 pixel (256 × 128 SPAD) dToF imager that overcomes these limitations by using pixels with embedded histogramming, which lock onto and track the return signal. This reduces the size of output data frames considerably, enabling maximum frame rates in the 10 kFPS range or 100 kFPS for direct depth readings. The sensor offers selective readout of pixels detecting surfaces, or those sensing motion, leading to reduced power consumption and off-chip processing requirements. We demonstrate the application of the sensor in mid-range LIDAR.

Image Sensors World        Go to the original article...

Hybrid bonding technology is rapidly becoming a standard approach in chipmaking due to its ability to increase connection densities.
This webinar will:
  • Examine different hybrid bonding approaches implemented in recent devices
  • Discuss key players currently using this technology
  • Look to the future of hybrid bonding, discussing potential wins – and pitfalls – to come.
This presentation compiles content from TechInsights’ subject matter experts in Memory, Image Sensor, and Logic, and from Engineers specializing in a variety of reverse engineering techniques. Many of these experts will be on hand for the live Q&A session following the presentation.

A preview of the topics that will be discussed:

Advanced Logic

First saw Chip on Wafer (CoW) hybrid bonding technology in the AMD Ryzen 7.
Stacking memory directly with the processor greatly increases available cache memory.
Milestone for system-technology-co-optimization (heterogeneous 3D scaling) described in the International Roadmap for Devices and Systems (IRDS) More Moore roadmap.
Image Sensors

We have seen Wafer-to-Wafer (W2W) stacking since 2016 from Sony.
Bond pitches as small as 2.2 µm are common, and the trend points to pitches as small as 1.4 μm.
Direct bond interconnect will ultimately enable digital pixel with in-pixel ADC and stacking of three or more wafers.

Hybrid bonding often used in High Bandwidth Memory (HBM) and 3D Xtacking applications.
Hybrid bonding will be one of most important high density memory enablers.
Further scaling, greater cost effectiveness, fewer defects, and solutions to thermal issues are still required.

Samsung announces 200MP ISOCELL HPX

Image Sensors World        Go to the original article...


Samsung has announced the ISCOCELL HPX, a new 200MP sensor in China. This follows the June announcement of the ISOCELL HP3 200MP sensor. The ISOCELL HPX has 0.56-micron pixel size, which can reduce the camera module area by 20%, making the smartphone body thinner and smaller.

Furthermore, Samsung employed Advanced DTI (Deep Trench Isolation) technology, which not only separates each pixel individually, but also increases sensitivity to capture crisp and vivid images. Furthermore, the Super QPD autofocus solution enables ISOCELL HPX to have ultra-fast and ultra-precise autofocus.

Tetra-Pixel technology in ISOCELL HPX sensor

Additionally, the Tetra pixel (16 pixels in one) technology is used in this new sensor that will give positive shooting experience in low light. With the help of this technology, the ISOCELL HPX is able to automatically switch between three different lighting modes depending on the available light: in a well-lit environment, the pixel size is maintained at 0.56 microns (μm), rendering 200 million pixels; in a low-light environment, the pixel is converted to 1.12 microns (μm), rendering 50 million pixels; and in a low-light environment, 16 pixels are combined to create a 2.24 micron (μm) 12.5 million pixel sensor.

According to Samsung, this technology enables ISOCELL HPX to deliver a positive shooting experience in low light and to reproduce sharp, sharp images as much as possible, even when the light source is constrained.

The ISOCELL HPX supports seamless dual HDR shooting in 4K and FHD modes and can capture 8K video at 30 fps. Depending on the shooting environment, Staggered HDR, according to Samsung, captures shadows and bright lights in a scene at three different exposures: low, medium, and high. Then it’ll combine all three exposure photos to produce HDR images and videos of the highest quality.

Additionally, it enables the sensor to render the image at over 4 trillion colours (14-bit colour depth), which is 64 times more than Samsung’s forerunner’s 68 billion colours (12-bit colour depth).

There’s no official wording from the firm regarding the availability. We should know in the coming weeks.

Atomos completes development of world class 8K video sensor and is exploring commercialisation
[Oct 5, 2022]

Atomos announces that it has completed development of a world class 8K video sensor to allow video cameras to record in 8K ultra high resolution

8K Ultra HD televisions are already in the market from Samsung, Sony and LG but 8K content has been lagging 

The Company is exploring opportunities to commercialise its unique IP and is in discussion with several camera makers

Atomos Limited (‘ASX:AMS’, ‘Atomos’ or the ‘Company’) is pleased to announce that it has completed development of  a  world  class  8K  video  sensor    which  allows  cameras  to  record  in  8K  ultra  high  definition. 

Atomos acquired the intellectual property rights   and technical team from broadcast equipment firm, Grass Valley five years ago to develop a leading-edge 8K video sensor.

8K video has four times the resolution of 4K video and allows video creators much greater flexibility when  zooming in  or  cropping their  shots  during  editing,  as  the  resulting  shot  maintains  sharp resolution. 

There  are  several  8K  televisions  already  in  the  market  from  Samsung,  Sony  and  LG  and  8K  gaming  consoles are expected soon.  8K content however has  been  lagging  because,  outside  of  big  camera  makers such as Sony, owning 8K sensor technology is extremely rare.

Development of Atomos’ 8K sensor is now complete. The Company is actively exploring opportunities for commercialisation and is in discussion with several camera makers who are showing great interest.

IC Insights article on CMOS Image Sensors Market

CMOS Image Sensors Stall in ‘Perfect Storm’ of 2022

For most of the last two decades strong growth in CMOS image sensors pushed this product category to the top of the optoelectronics market, in terms of sales volume, generating over 40% of total opto-semiconductor annual revenues. In 2022, however, the CMOS image sensor market category is on track to suffer its first decline in 13 years with sales expected to fall 7% to $18.6 billion and unit shipments projected to drop 11% to 6.1 billion worldwide, according to IC Insights’ August 3Q Update of The McClean Report service (Figure 1).

The projected 2022 decline in CMOS image sensors comes after two years of meager sales growth in 2020 (+4%) and 2021 (+5%).  This year’s sales drop reflects overall weakness in consumer smartphones and portable computers with digital cameras for video conferencing following an upsurge in demand for Internet connections and online conferencing capabilities during the Covid-19 virus pandemic.  The 3Q Update forecast shows a modest recovery in CMOS image sensors next year with market revenues growing 4% to $19.3 billion and then rising 13% in 2024 to reach a new record high of $21.7 billion.

In addition to weak demand in mainstream consumer camera cellphones and portable computers, CMOS image sensors have been negatively impacted by deteriorating global economic conditions resulting from high inflation and spiking energy costs caused by the Russian war in Ukraine as well as U.S. trade bans on China, recent Covid-19 virus lockdowns in Chinese manufacturing centers, and slowing growth in the number of cameras being packed inside of new smartphones.  Some high-end smartphone models contain five or more cameras, but the average in most handsets has stayed at three (one on the front, facing the user for “selfie” photos and two main cameras on the backside of phones).  IC Insights’ 3Q Update Report says some managers in China have described the image sensor market conditions as a “perfect storm,” combining a slowdown in mainstream mid-range smartphone shipments and an unanticipated pause in the increase of embedded cameras being designed in new handsets.

CMOS image sensor market leader Sony—which accounted for about 43% of CMOS image sensor sales worldwide in 2021—reported a 12.4% sequential decline in image sensor dollar-volume revenues (-2% in Japanese yen) during the company’s fiscal 1Q23 quarter, ended in June 2022.  In the first half of calendar 2022, Sony struggled to match image-resolution requirements for camera phones and its CMOS image sensor sales to leading Chinese system manufacturers were lowered by U.S. trade bans.  Sony still believes excess inventories of phones and image sensors will be reduced by early 2023 and market conditions will “normalize” in the second half of its current fiscal year (ending next March).

Nearly two-thirds of CMOS image sensors are used in cellphones, and that share is expected to fall to about 45% by 2026, according to The McClean Report’s 3Q Update.  A slow–but-steady recovery in CMOS image sensors is forecast to be driven by a new upgrade buying cycle of smartphones and more embedded cameras being added in other systems, especially for automotive automation capabilities, medical applications, and intelligent security networks.  The 3Q Update shows CMOS image sensor sales rising by a CAGR of 6.0% between 2021 and 2026 to reach $26.9 billion in the final year of the forecast.  CMOS image sensor shipments are forecast to grow by a CAGR of 6.9% between 2021 and 2026, reaching 9.6 million units.

Author: Shuo Wang, Jan Dirk Schulze Spüntrup, Björn Albrecht, Christine Harendt, Joachim Burghartz
Affiliation: Institut für Mikroelektronik Stuttgart IMS CHIPS, Germany

Abstract: Unlike most image sensors, which are planar and inflexible, in this work, an ultra-thin image sensor is performed as a Hybrid System in Foil (HySiF) by using Chip-Film Patch technology, which is a concept for high-performance and ultra-thin flexible electronics. In order to characterize this image sensor embedded in foil, an adapter board for the Andvantest 93000SOIC test system was developed. This paper demonstrates production process of the HySiF and its´ behavior and performance. In addition, the applications and future work of this bendable image sensor in foil system is discussed.
