AutoSens Detroit publishes Aeye VP of Engineering, Barry Behnken, presentation of the adaptive scanning iDAR. Aeye says that in SNR-starved environment, it does not make sense to spend the precious laser photons on "uninteresting" objects, such as sky, empty road, top floors of buildings, etc. Rather, the company proposes to concentrate them on the object that a regular 2D camera points as "interesting." The 2D camera info can be combined with other sources of info, such as radar, ultrasonic sensors, GPS, etc.
MDPI Sensor publishes " A Review of Ion Implantation Technology for Image Sensors " by Nobukazu Teranishi, Genshu Fuse, and Michiro Sugitani from Shizuoka and Hyogo Universities and Sumitomo. " Image sensors are so sensitive to metal contamination that they can detect even one metal atom per pixel. To reduce the metal contamination, the plasma shower using RF (radio frequency) plasma generation is a representative example. The electrostatic angular energy filter after the mass analyzing magnet is a highly effective method to remove energetic metal contamination. The protection layer on the silicon is needed to protect the silicon wafer against the physisorbed metals. The thickness of the protection layer should be determined by considering the knock-on depth. The damage by ion implantation also causes blemishes. It becomes larger in the following conditions if the other conditions are the same; a. higher energy; b. larger dose; c. smaller beam size (higher beam current d...
