Solid-state imaging device, production method, and electronic apparatus

A method of producing a solid-state imaging device including a pixel array having a plurality of pixels, comprising:

• forming color filters on a substrate;
• forming a first lens layer on the color filters;
• and
• forming a first film on the first lens layer;
• forming a second lens layer on the first film;
• and
• forming a second film on the second lens layer;
• forming a third lens layer on the second film,
• wherein each of the first film and the second film and each of the first, second, and third lens layers is a contiguous and unitary layer that spans across all of the plurality of pixels,
• wherein light incident to the color filters passes through the first, second, and third lens layers, the first film, and the second film, and
• wherein the first film and the second film have a lower refractive index than the plurality of lens layers.

An electronic apparatus, comprising:

• a solid-state imaging device including:
• a pixel array having a plurality of pixels, each pixel including:
• a color filter;
• a photoelectric conversion unit;
• a microlens including a plurality of lens layers;
• a first film formed between a first lens layer of the plurality of lens layers and a second lens layer of the plurality of lens layers;
• and
• a second film formed between the second lens layer and a third lens layer in the plurality of lens layers,
• wherein each of the first film and the second film and each of the plurality of lens layers is a contiguous and unitary layer that spans across all of the plurality of pixels,
• wherein light incident to the color filter passes through the plurality of lens layers, the first film, and the second film, and
• wherein the first film and the second film have a lower refractive index than the plurality of lens layers.
