Pandemics And Panic Chip Buying


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


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.

CMOS Image Sensors (CIS): Past, Present & Future


Over the last decade, CMOS Image Sensor (CIS) technology has made impressive progress. Image sensor performance has dramatically improved over the years, and CIS technology has enjoyed great commercial success since the introduction of mobile phones using onboard cameras. Many people, including scientists and marketing specialists, predicted 15 years earlier that CMOS image sensors were going t... » read more
