SOLID-STATE IMAGE-PICKUP ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a solid state image-pickup element which can increase condensing efficiency and sensitivity by preventing reflection which occurrs between a within-layer lens and its upper or lower layer. SOLUTION: This element includes a light-receiving sensor part 3 provided on a surface layer part of a substrate 2 for photoelectric conversion, a charge transfer part 5 for transferring a signal charge read out by the sensor part 3, and a transfer electrode 8 provided above the substrate 2 and nearly directly above the charge transfer part 5 through an insulating film 7. Provided above the sensor part 3 is a within-layer lens 15 for condensing an incident light into the sensor part 3. A color filter layer 17 is provided above the within-layer lens 15 through an anti-upward-reflection film 16. The film 16 is made of a material which has a refractive index between that of the lens 15 and that of the color filter layer 17.
