CMOS pixels and visible light image sensors

Abstract: Visible-light image sensors have become a commodity and are now indispensible to modern life. Every cellular phone, tablet PC, and laptop computer hosts one or more image sensors that have been manufactured using CMOS technology. Before the early 2000s, CCD technology was used in most cameras. Then, scientists and technologists realized that more-inexpensive CMOS semiconductor technology could be customized to produce image sensors that would potentially exceed the quality of a CCD sensor. Attracted by the forecast high volume of CMOS sensors, major silicon foundries also introduced dedicated lines and unique fabrication steps to turn out custom CMOS image sensors. Today, the CMOS image-sensor market far surpasses the CCD market. From professional broadcast cameras and DSLRs to inexpensive point-and-shoot cameras, CCD sensors are fast disappearing from the scene. This seminar describes today’s state of the art in CMOS image sensors, and explains why CMOS technology is the winner for visible-imaging cameras.
