  • Solid state image sensing device with a color filter
    Patent number: 4600833
    Abstract: A solid state image sensing device comprises a photosensitive semiconductor element having a plurality of photocells on a surface thereof. A protective layer is disposed on the photosensitive semiconductor element, and an inorganic layer is disposed on the protective layer. A plurality of color filter layers each comprising a coloring agent having a color absorption characteristic are mixed into a portion of the inorganic layer in locations overlying the photocell, and a surface protective coating is disposed on a surface of the color filter layers.
