technology. At first, we did not understand anything about the differences when compared with electronics products and the unique culture of the automotive industry, but we learned by reading standards and attending seminars, all the while striving to improve. Ikeda: We at Sony have built up expertise at our production bases in Japan over many years and have managed to realize image sensors with high sensitivity and less noise. In addition to image sensors, this collaboration between the two companies from Belgium and Japan also contributed to securing the iToF businesses. The other issue related to how best to make electronic connections between the pixel chip and the circuit chip on two different layers. ToF camera module for smartphones(module with the IMX316), Automotive Business Dept.Automotive Business Div.Sony Semiconductor Solutions Corporation. They cannot be located in the pixel area because of this penetration and require dedicated spaces. It also offers high-sensitivity performance capable of producing high-quality color images even in light conditions as low as 0.1 lux, which is equivalent to moonlight. ※4 The result is the world’s smallest ※1 type 1/2.8 4K-resolution stacked CMOS image sensor yet with superior low-light performance. Creating a world filled with emotion. ──What is epoch-making about the development of the back-illuminated CMOS image sensors? Tokyo, Japan - Sony Corporation ("Sony") is announcing the commercialization of a new 2.45 effective megapixel CMOS image sensor for automotive cameras, the IMX390CQV type 1/2.7. The image sensors use technology that guarantees a long enough exposure to capture the LED while preventing pixel saturation caused by bright subjects, as well as unique pixel structures and exposure methods to achieve simultaneous HDR and LFM functions. It is used for face recognition in smartphones, features related to AR and VR, and autonomous robots and drones. For the next generation. Development of back-illuminated CAPD uncovered synergies with Sony’s device and circuit technology. 2.45 megapixels, MIPI CSI-2 serial output (4 lane / 2 lane), Sony Commercializes the Industry's First High-Sensitivity CMOS Image Sensor for Automotive Cameras, Delivering Simultaneous LED Flicker Mitigation and High-Quality HDR Shooting, Planned to meet the AEC-Q100 Grade 2 automotive electronic component reliability requirements this fiscal year, Development process complies with ISO26262 automobile functional safety standards, resulting in a high level of design quality, Sensor meets ASIL C functional safety requirements. This world-first technology rearranges the pixel and circuit sections, which were previously placed on the same silicon chip, into two separate layers. For example, since it is so hot inside and outside the car in summer, automotive image sensors need to operate in a wide range of temperature conditions. Although a transition from CCD to CMOS image sensors was occurring for certain applications, the image quality of front-illuminated CMOS image sensors had room for improvement, and the transition itself brought up a number of issues. SWIR stands for "Short Wavelength Infra-Red." April 12, 2017 In the back-illuminated structure, the pixel chip on the upper layer is thinned to be about 10 μm thick, a fifth of the usual thickness, following the wafer-on-wafer bonding process. Delivering Excitement, Passion, Joy and Compassion to the World. This image sensor uses original Sony pixel structure and exposure methods to achieve the industry's first*1-ever simultaneous LED flicker mitigation and HDR functions. Dept. Later, we verified that it was necessary to make the circuit patterns on the lower layer ultra-flat prior to the wafer-on-wafer bonding, and it took about two years to succeed with the stacking. The upper limit is currently around 125℃. The Sony CMOS Image Sensor sensor is simply another step for Sony within the world of high definition video cameras, making it something you cannot fail with. 1Sony Semiconductor Solutions Corporation. To solve this, we developed substrate bonding technology to flip the photodiode substrate, high precision grinding technology to control the thickness of the substrate, and technology to suppress the noise during the grinding process. Noritaka Ikeda: These image sensors are used in sensing and viewing cameras for autonomous driving (AD) and advanced driver-assistance systems (ADAS). It was a difficult journey, but Sony became the first in the world to achieve mass production. In addition, Sony’s stacked CMOS image sensor technology helps with further differentiation. By making Sony Semiconductor Solutions’ team small too, requiring each member to be more responsible, we were able to realize rapid development while absorbing this unfamiliar culture. We asked those involved to tell us more about these products and technologies and give us a peek into how they came to be developed. AI models can be rewritten and updated with the latest AI models to match various system environments and conditions. It is mainly used for stacked image sensors used in smartphones and contributes to miniaturization and greater functionality of chips. Exmor R was announced by Sony on 11 June 2008 and was the world's first mass-produced implementation of the back-illuminated sensor technology. The new image sensor features an original Sony pixel structure and exposure method that delivers an HDR function capable of 120dB. ──Please tell us a little about stacked CMOS image sensors. As well as expertise in developing system LSI, Sony had other necessary technologies such as back-illuminated CMOS image sensors, stacked CMOS image sensors, and Cu-Cu direct bonding that allow for high quality image capturing and multiple simultaneous functions.
