Abstract
An imaging apparatus according to the present invention includes a substrate including a plurality of pixel circuits arranged thereon and a semiconductor layer disposed on the substrate. Each of the plurality of pixel circuits includes an amplification transistor configured to output a signal based on charge generated in the semiconductor layer. The charge generated in the semiconductor layer is transferred in a first direction parallel to a surface of the substrate.
Claims21
An imaging apparatus comprising:
- a substrate including a plurality of pixel circuits;
- first, second, third, and fourth electrodes disposed on the substrate;
- and
- a semiconductor layer disposed on the substrate and including a first portion and a second portion,
- wherein
- the first portion is disposed between the first electrode and the second electrode and is formed vertically above the second electrode and within a boundary of the second electrode,
- the second portion is disposed between the third electrode and fourth electrode and is formed vertically above the fourth electrode and within a boundary of the fourth electrode,
- each of the plurality of pixel circuits includes an amplification transistor configured to output a signal based on charge generated in the semiconductor layer, and
- the charge generated in the semiconductor layer is accumulated in the first portion, and thereafter transferred from the first portion to the second portion in a first direction parallel to a surface of the substrate.
