Abstract
A solid-state image pickup element equipped with a film stack, a color filter, and a microlens on a semiconductor substrate equipped with a light receiving section, comprises a first film with a high refractive index and a second film with a low refractive index adjacently arranged on the semiconductor substrate in this order viewing from the semiconductor substrate side, each of which has at least one layer respectively. Thereby it makes possible to reduce the loss of incident light, and to achieve the enhancement in photoelectric conversion efficiency.
Claims23
A solid-state image pickup element including a semiconductor substrate, a light receiving section formed on the semiconductor substrate, and a signal transfer section which is formed on the semiconductor substrate and transfers a signal generated in the light receiving section, comprising,
- a first film with a high refractive index and a second film with a low refractive index adjacently arranged in this order viewing from the semiconductor side, each of which has at least one layer.
A solid-state image pickup element, comprising a semiconductor substrate, a light receiving section formed on the semiconductor substrate, an electric charge transfer section formed on the semiconductor substrate and transfers electric charges formed on the light receiving section and an anti-reflection film formed above the light receiving section,
- wherein at least one layer constructing the anti-reflection film is produced by a coating method.
