Abstract
In a pixel part, in a first active region, a photodiode and a transferring transistor are formed. In a second active region, a resetting transistor is formed. In a pixel part, in a first active region, a photodiode and a transferring transistor are formed. In a second active region, an amplifying transistor is formed. The first and second active regions are respectively the same in shape in image pixel parts. The resetting transistor and the amplifying transistor are shared by the pixel parts.
Claims5
An image sensor comprising:
- a first image pickup element, and
- a second image pickup element, wherein
- each of said first and second image pickup elements comprises
- a first photoelectric conversion element,
- a second photoelectric conversion element,
- a first transferring transistor, one terminal of which is connected to said first photoelectric conversion element,
- a second transferring transistor, one terminal of which is connected to said second photoelectric conversion element,
- a reset transistor, one terminal of which is connected to another terminal of said first transferring transistor and another terminal of said second transferring transistor, and
- an amplifying transistor, a control terminal of which is connected to said another terminal of said first transferring transistor and said another terminal of said second transferring transistor, wherein
- said first photoelectric conversion elements of said first and second image pickup elements are arranged along a first direction, wherein
- each of said second photoelectric conversion elements is arranged along a second direction relative to each of said first photoelectric conversion elements in the same image pickup element, and wherein
- a first portion of an interconnection layer between said another terminal of said first transferring transistor and said control terminal of said amplifying transistor is arranged along said second direction to a first side of said second photoelectric conversion element in said first image pickup element, a second portion being the same material as said first potion is arranged along said second direction to a first side of said first photoelectric conversion element in said first image pickup element.
