Title:
SOLID IMAGING DEVICE AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2007/043226
Kind Code:
A1
Abstract:
A solid imaging device comprising a plurality of photodiodes regions (2) arranged
in an array, opaque boundary regions (6) existing around the respective photodiodes
regions, and a micro lens array (8a) including a plurality of micro lenses arranged
in an array to correspond to the plurality of photodiodes regions, wherein the
respective micro lenses act to condense incident lights (7) directly advancing
toward opaque boundary regions around the corresponding photodiode regions
into the corresponding photodiode regions, the micro lens array is formed using
a translucent DLC film, the DLC film a contains region where a refractive index
is modulated in association with each micro lens, and a condensing action occurs
when a light beam passes through the refractive index-modulated region.
