An electronic device may include a photoelectric element, a shielding layer on the photoelectric element, and a color filter structure on the shielding layer. The shielding layer may define a first opening over the photoelectric element. The color filter structure may define a second opening over the photoelectric element and the first opening. The color filter structure may appear dark from a view facing the color filter structure.

Image sensor and method for fabricating the same

An image sensor may include a substrate which includes a plurality of block regions. Each block region may include a separate plurality of pixel regions. Each pixel region may include a separate photoelectric element of a plurality of photoelectric elements in the substrate and a separate micro lens of a plurality of micro lenses on the substrate. Each micro lens of the plurality of micro lenses may be laterally offset from a vertical centerline of the pixel region towards a center of the block region. Each block region of the plurality of block regions may include a common shifted shape of the plurality of micro lenses of the block region.

Image sensors

The image sensor includes a substrate, an insulating structure formed on a first surface of the substrate and including a first metal wiring layer exposed by a contact hole penetrating the substrate, a conductive spacer formed on sidewalls of the contact hole and electrically connected to the first metal wiring layer, and a pad formed on a second surface of the substrate and electrically connected to the first metal wiring layer.

Image sensor and method of fabricating the same

In a solid state imaging device, and a method of manufacture thereof, the efficiency of the transfer of available photons to the photo-receiving elements is increased beyond that which is currently available. Enhanced anti-reflection layer configurations, and methods of manufacture thereof, are provided that allow for such increased efficiency. They are applicable to contemporary imaging devices, such as charge-coupled devices (CCDs) and CMOS image sensors (CISs). In one embodiment, a photosensitive device is formed in a semiconductor substrate. The photosensitive device includes a photosensitive region. An anti-reflection layer comprising silicon oxynitride is formed on the photosensitive region. The silicon oxynitride layer is heat treated to increase a refractive index of the silicon oxynitride layer, and to thereby decrease reflectivity of incident light at the junction of the photosensitive region.
