Patent 10375334 was granted and assigned to Sony on August, 2019 by the United States Patent and Trademark Office.
The present technology relates to an image sensor and an electronic apparatus which can make the image sensor a smaller without degrading performance of the image sensor. The image sensor includes a pixel array unit in which pixels including photoelectric conversion elements are arranged in a two dimensional manner, a row circuit configured to control row scanning of the pixel array unit, and a column processing unit configured to convert an analog signal read out from the pixel array unit into a digital signal. The pixel array unit is disposed on a first-layer substrate, and the row circuit and the column processing unit are disposed on different substrates which are underlying layers of the first-layer substrate and which are laminated on the first-layer substrate. The present technology is applicable to the image sensor.
