CCD solid state imager

Abstract

Abstract A flattened layer (6) formed between a micro-condenser lens (7) and an Aℓ light-shielding layer (5) is formed as a bilayer and this bilayer is formed by sequentially laminating a first layer (6a) and a second layer (6b) having a refractive index (N₂) lower than a refractive index (N₁) of the first layer (6a). Therefore, of the incident light converged by the micro-condenser lens (7), a light component shielded by the shoulder portion of the Aℓ light-shielding layer (5) is reduced and a sensitivity increasing effect, which is an effect inherent in the condenser lens, can be demonstrated sufficiently, which can make the CCD solid state imager compact in size and which can improve the image quality.
