Abstract
A solid-state imaging device is provided. The solid-state imaging device includes a semiconductor substrate containing a plurality of photoelectric conversion elements. A color filter layer includes a first color filter component and a second color filter component separated from each other and disposed above the semiconductor substrate. A microlens structure includes a first microlens element and a second microlens element separated from each other and disposed on the first and second color filter components respectively. The solid-state imaging device also includes a gap filled with air. The gap is disposed between the first and second color filter components and also between the first and second microlens elements.
