Title:
SOLID IMAGING DEVICE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2009302483
Kind Code:
A
Abstract:

To provide a solid imaging device that suppresses a variation of sensitivity between pixels.

In the solid imaging device 100 having a plurality of unit pixels 101 disposed in a matrix shape, each of the plurality of the unit pixels 101 includes a photodiode 111 for converting light into an electric signal, a top lens 210 for collecting incident light, and an intra level lens 206 for collecting the incident light collected by the top lens 210 into the photodiode 111. The gravity center 302 of the photodiode 111 is displaced to a first direction from the center 301 of the unit pixel 101. The top lens 210 is formed in an asymmetrical shape so that the gravity center 303 is displaced to the first direction from the center 301 of the unit pixel 101. The intra level lens 206 is formed so that the gravity center 304 is displaced to the first direction from the center 301 of the unit pixel 101.
