Image Sensors Are Everywhere And The Implications For Test Are Significant
By Tom Chambers - 11 Apr, 2023 - Comments: 0

In February of 2021, the NASA Perseverance rover actively navigated a fully-autonomous entry and descent to successfully land in the Jezero Crater on Mars, using a brand-new navigational system developed by NASA – Terrain-Relative Navigation. The delay between mission control and the rover was about 11 minutes so a human-guided remote landing was not possible. Previous missions had to rely o... » read more

A new technical paper titled "A processing-in-pixel-in-memory paradigm for resource-constrained TinyML applications" was published by researchers at University of Southern California (USC). According to the paper, "we propose a novel Processing-in-Pixel-in-memory (P2M) paradigm, that customizes the pixel array by adding support for analog multi-channel, multi-bit convolution, batch normaliza... » read more

A novel technique for random number generation using CMOS image sensor
By Technical Paper Link - 04 Apr, 2022 - Comments: 0

Academic paper from Thamirabharani Engineering College, India. Abstract "Random Number Generators (RNGs) have been used in several traditional fields such as simulation, gaming, cryptography, etc. Random numbers are used in cryptography to generate passwords. The strength of a password depends not just on its length and complexity but mainly on its unpredictability. Strong passwords lower t... » read more

Critical Moves: Advanced Logic Devices And CIS Benefit From Applications Using IRCD Metrology
By Nick Keller - 08 Feb, 2022 - Comments: 1

As 3D NAND continues to scale vertically — all in the name of increasing capacity and speed and reducing inefficiency and cost — maintaining channel hole critical dimension (CD) and shape uniformity becomes even more challenging. Faced with rising high-aspect ratios, addressing these challenges requires new inline non-destructive metrology to provide real-time process control. Infrared crit... » read more

Understanding Optical Inspection For CIS
By Woo Young Han - 11 May, 2021 - Comments: 0

The demand for smartphone cameras, video conferencing, surveillance and autonomous driving has fueled explosive growth of CMOS image sensor (CIS) manufacturing in the last decade. While CIS becomes an increasingly important element in the production of today’s consumer electronics, there are unique challenges in production that must be addressed. As pixel sizes shrink, we see an inverse relat... » read more

A Look Inside ADAS Modules
By Prasad Dhond - 21 Jan, 2021 - Comments: 0

You glance down at your phone while rolling in slow-moving traffic. Against your better judgment, you proceed to read your latest email, oblivious to the fact that the car in front of you has braked. In the nick of time, your car starts beeping and flashing. You look up and slam the brakes. Whew! That was close. If this has happened to you, don't forget to thank the radar and camera modules in ... » read more

Startup Funding: October 2020
By Jesse Allen - 02 Nov, 2020 - Comments: 0

October 2020 was a big month for startups across the automotive space, with sizeable funding all around. Three startups based out of China brought in over $100M apiece for ADAS and autonomous driving, and a fourth U.S.-based startup saw $125M investment for simulating and testing autonomous driving systems. Two electric vehicle manufacturers also received $100M+ rounds. Collectively, the auto c... » read more

Pandemics And Panic Chip Buying
By Mark LaPedus - 18 Jun, 2020 - Comments: 0

U.S.-China trade tensions are creating uncertainty in the semiconductor market, but it is also causing another event right now—panic chip buying. At present, some but not all foundry vendors are seeing “rush orders” for select products and are running their fabs at full capacity. It’s not just leading-edge devices, but also mature technologies. A surge of chip orders started in Ma... » read more

Advances In 3D CMOS Image Sensors Optical Modeling: Combining Realistic Morphologies With FDTD
By Coventor - 16 Oct, 2019 - Comments: 0

This paper describes an innovative methodology to investigate the relationship between device morphology and the optical performance of CMOS image sensors. By coupling a FDTD-based 3D Maxwell solver with silicon-accurate process modeling software, we have been able to analyze the sensitivity of image sensor quantum efficiency with respect to statistical variations in nm-scale device topology. A... » read more
