IMAGE SENSOR, MANUFACTURING METHOD OF THE SAME, AND IMAGE PROCESSING SYSTEM INCLUDING THE IMAGE SENSOR

摘要

An image sensor is provided. The image sensor includes a photoelectric converter formed on a first layer and configured to generate light charges by receiving light, a read circuit formed on a second layer below the first layer and configured to accumulate the generated light charges and produce a video signal according to an amount of the accumulated light charges, and a light charge transfer layer formed on a third layer between the first and second layers and configured to transfer the generated light charges to the read circuit. The read circuit includes a single transistor, and the light charges are accumulated in a body of the single transistor.
