  • Patent number: 10008529
    Abstract: The present disclosure relates to a solid-state imaging device that enables diffusion of components in the interfaces between microlenses and an antireflection film, a method of manufacturing the solid-state imaging device, and an electronic apparatus. Moisture permeation holes are formed between the microlenses of adjacent pixels. The moisture permeation holes are covered with an antireflection film. The antireflection film is formed on the surfaces of the microlenses excluding the diffusion holes. The refractive index of the antireflection film is higher than the refractive index of the microlenses. The present disclosure can be applied to complementary metal oxide semiconductor (CMOS) image sensors that are back-illuminated solid-state imaging devices, for example.
