Counterpoint Research publishes its estimation on automotive image sensor market shares: "The automotive camera sensor market is consolidated with ON Semiconductors accounting for around 50% of market share, followed by Omnivision, Sony and Toshiba, each accounting for 12-18% of market share. Other important players in the market includes Gentex and Melexis. The competition in the market is increasing with players introducing technologically advanced sensors."
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...
