Full textThe production test of the CMOS imagers is realized with testers that use light sources precise. This need make the imagers test complicated and expensive. Moreover, these kinds of tests can not be realised directly on the imager in order to incorporate auto test functions. These functions are interesting for the reduction of the production test costs and for the diagnosis of the imager. The diagnosis is important during the production and when the imagers have been submitted to important stress sources. In general, the users of the imagers seldom own the equipment necessary to verify its functionality. In this work, we study and evaluate a Built-In-Self-Test (BIST) technique for the CMOS vision sensors. This technique realises a structural test of the imager. The structural test is based on electrical stimuli applied to the photodiode anode and to the pixel transistors. The BIST quality is evaluated by the test metrics that takes into account process variations and the presence of catastrophic and single parametric faults. The BIST is evaluated for two kinds of imagers, the first one uses integrations pixels and the second one logarithmic pixels. An experimental validation is done for the logarithmic imager

Full textWith the increase of systems complexity, integrating different technologies together has become a major challenge. Another challenge has traditionally been the limitation on the throughout between different part of the system coming from the interconnections. If traditional two dimensional integration solutions like System In a Package (SIP) bring heterogonous technologies together there is still limitations coming from the restricted number and lengths of interconnections between the different system components. Three Dimensional stacking (3D), by exploiting short vertical interconnections between different circuits of mixed technologies, has the potential to overcome these limitations. Still, despite strong interests for the 3D concepts, there is no advanced analysis of 3D integration benefits, especially in the field of imagers and smart image sensors. This thesis study the potential benefits of 3D integration, with local processing and short feedback loops, for the realisation of a High Dynamic Range (HDR) image sensor. The dense vertical interconnections are used to locally adapt the integration time by group of pixels, called macro-pixels, while keeping a classic pixel architecture and hence a high fill factor. Stacking the pixel section and circuit section enables a compact pixel and the integration of flexible and versatile functions. High Dynamic Range values producing an important quantity of data, the choice has been made to implement data compression to reduce the circuit throughout. A first level of compression is produced by coding the pixel value using a floating format with a common exponent shared among the macro-pixel. A second level of compression is proposed based on a simplified version of the Discrete Cosine Transform (DCT). Using this two level scheme, a compression of 93% can be obtained with a typical PSNR of 30 dB. A validation of the architecture was carried out by the development; fabrication and test of a prototype on a 2D, 180 nm, CMOS technology. A few pixels of each macro-pixel had to be sacrificed to implement the high dynamic range control signals and emulate the 3D integration. The test results are very promising proving the benefits that will bring the 3D integration in term of power consumption and image quality compared to a classic 2D integration. Future realisations of this architecture, done using a real 3D technology, separating sensing and processing on different circuits communicating by vertical interconnection will not need the sacrifice of any pixel to adjust the integration time, improving power consumption, image quality and latency

Full textToday, space imaging is an essential tool for sustainable development, research and scientific innovation as well as security and defense. Thanks to their good electro-optic performances and low power consumption, CMOS image sensors are serious candidates to equip future space instruments. However, it is important to know and understand the behavior of this imager technology when it faces the space radiation environment which could damage devices performances. Many previous studies have been focused on ionizing effects in CMOS imagers, showing their hardness and several hardening-by-design techniques against such radiations. The conclusions of these works emphasized the need to study non-ionizing effects which have become a major issue in the last generation of CMOS image sensors. Therefore, this research work focuses on non-ionizing effects in CMOS image sensors. These effects, also called displacement damage, are investigated on a large number of CMOS imagers and test structures. These devices are designed using several CMOS processes and using design rule changes in order to observe possible common behaviors in CMOS technology. Similarities have been shown between proton and neutron irradiations using current-voltage characteristics and deep level transient spectroscopy. These results emphasize the relevance of neutron irradiations for an accurate study of the non-ionizing effects. Then, displacement damage induced dark current increase as well as the associated random telegraph signal are measured and modeled. Common evaluation parameters to investigate displacement damage are found, allowing imager behavior prediction in space radiation environment. Finally, specific methods and hardening-by-design techniques to mitigate displacement damage are proposed

Full textThis research aims to develop a vision system with low energy consumption for Wireless Sensor Networks (WSNs). The imager in question must meet the specific requirements of multimedia applications for Wireless Vision Sensor Networks. Indeed, a multimedia application requires intensive computation at the node and a considerable number of packets to be exchanged through the transceiver, and therefore consumes a lot of energy. An obvious solution to reduce the amount of transmitted data is to compress the images before sending them over WSN nodes. However, the severe constraints of nodes make ineffective in practice the implementation of standard compression algorithms (JPEG, JPEG2000, MJPEG, MPEG, H264, etc.). Desired vision system must integrate image compression techniques that are both effective and with low-complexity. Particular attention should be taken into consideration in order to best satisfy the compromise "Energy Consumption - Quality of Service (QoS)"

Full textImaging has always been an interesting field, all the more so as it is nowpossible to see further than human eyes in the infrared and ultraviolet spectra. For each fieldof application, materials are more or less adapted : in order to capture visible light, Siliconis a good candidate, because it has been widely studied, and is also used in our everydaylife. Concerning the infrared, more particularly the MWIR spectral band, InSb has provedto be stable and reliable, even if it need to operate at cryogenic temperatures because ofa narrow bandgap.. In this work, a parasitic signal called Random Telegraph Signal (RTS)which appears in both materials (and also others, such as HgCdTe or InGaAs) is analyzed.This signal comes from the pixel photodiiode and corresponds to a discrete dark currentfluctuation with time, like blinking signals. This can cause detector calibration troubles, orfalse star detection for example. This study aims at characterizing RTS and localize the exactorigin in the photodiode in order to be able to predict or mitigate the phenomenon

Full textThis work has shown that the contribution of 3D integration technology allows to overcome the limitations imposed by monolithic technology on the electrical performances (coupling and consumption) and on the physical implementation (area of the pixel) of imagers. An in-depth analysis of the 3D integration technology has shown that the most suitable 3D integration technologies for the integration of the circuits at the pixel level are: 3D wafer level and 3D sequential construction. The technology chosen for this study is the 3D wafer level integration technology. This allows us to connect 2 wafers by thermocompression bonding and to have an interconnection or “bonding point” par pixel between wafers. The study of the architecture CAN at the pixel level showed that there are two limits in the pixel: the construction area and the coupling between the analog and digital part «digital coupling». Its implementation in 3D technology allows the construction area to be increased by 100% and the digital coupling reduced by 70%. It has been implemented a tool for computing the parasitic elements of 3D structures. The study of high speed imagers has allowed the use of this technology to be extended. The "burst" imager was mainly studied. This kind of imager’s architecture can dissociate the image acquisition from the output part. The main limit, in monolithic technology, is the size of the columns (pixels to memories). For a high rate of image acquisition, a high current consumption is required. Its implementation in 3D technology allowed to put the memories below the pixels. The studies carried out for this change (reduction of the column to an interconnection between wafers) reduced the total consumption by 90% and increased the acquisition time of the images by 184%, compared to its monolithic peer
