Imaging element and semiconductor chip

Abstract

The present technology relates to an imaging element and a semiconductor chip that enable the imaging element to be shorter. A first chip including a photodiode, and a second chip including a circuit configured to process a signal from the photodiode are laminated, and an impurity layer is provided on a second surface opposite to a first surface of the second chip on which the first chip is laminated. The impurity layer is formed to have an impurity concentration higher than an impurity concentration of a semiconductor substrate constituting the second chip. In the present technology, for example, an imaging element that is configured by laminating a plurality of chips and is shorter and smaller can be applied.
