An image sensor includes a substrate including a plurality of pixel regions and one or more pairs of dummy pixel regions; a pixel separation structure between two adjacent pixel regions among the plurality of pixel regions and including a first conductive layer; a dummy pixel separation structure between the one or more pairs of dummy pixel regions, electrically connected to the pixel separation structure, and including a second conductive layer; and a pixel separation contact disposed on the dummy pixel separation structure.

Image sensor

An image sensor includes a first pixel separation structure in a substrate to separate pixels from each other. The first pixel separation structure includes a conductive layer therein. Moreover, the image sensor includes a wire layer that is spaced apart from the conductive layer on the substrate. A second pixel separation structure is adjacent to the first pixel separation structure in a first horizontal direction and is connected to a contact. The first and second pixel separation structures extend longitudinally in a second horizontal direction that is perpendicular to the first horizontal direction.

Image sensor with conductive pixel separation structure and method of manufacturing the same

An image sensor and a method of manufacturing the image sensor are provided. The image sensor includes: a substrate comprising a pixel area, a first side, and a second side opposite to the first side, wherein the pixel area includes pixels and light is incident to the second side; a photodiode arranged in each of the pixels of the substrate; a pixel separation structure arranged in the substrate to separate the pixels from each other and including a conductive layer therein; and a voltage-applying wire layer spaced apart from the conductive layer and arranged to surround at least a portion of an outer portion of the pixel area. The conductive layer has a mesh structure that is a single unitary structure, and the voltage-applying wire layer is electrically connected to the conductive layer through at least one contact.

An image scanning method of an image scanning device, the method including: feeding multiply fed documents in a first path and scanning, by a scanning unit of the image scanning device, a first document of the multiply fed documents; outputting the first document through an exit unit; reversely driving the exit unit after the first document is output to reversely feed a second document of the multiply fed documents in a second path, and scanning the second document; and forming images of the first document and the second document, wherein the second path is used to reversely feed the second document to an upstream side of the scanning unit, in view of a feeding direction of the multiply fed documents.
