Patent ID: 7649166

Claim:
An imaging device, comprising: (a) a plurality of first electrode strips in parallel to each other along a first direction, wherein each first electrode strip has an elongated body with a first surface and an opposite, second surface and a thickness n 1 ; (b) a plurality of second electrode strips in parallel to each other along a second direction that is substantially perpendicular to the first direction, wherein each second electrode strip has an elongated body with a first surface and an opposite, second surface and a thickness n 2 , and wherein the plurality of second electrode strips are positioned apart from the plurality of first electrode strips along a third direction that is substantially perpendicular to the first direction and the second direction such that the plurality of first electrode strips and the plurality of second electrode strips are crossing each other accordingly to form a corresponding number of crossing points; and (c) at each crossing point, a semiconductor component is filled between the second surface of a corresponding first electrode strip and the first surface of a corresponding second electrode strip to form an addressable pixel, wherein the semiconductor component has a thickness n s that satisfies the following relationship: n s ≧n 1 , n 2 , and wherein, in operation, when an illuminating light containing information of an object is incident onto the first surface of a first electrode strip of an addressable pixel, a corresponding imaging signal is generated at the second surface of the corresponding second electrode strip.
