Abstract:
The present disclosure relates to an imaging element, a fabrication method, and electronic equipment by which an image having higher picture quality can be imaged. The imaging element includes a first light absorbing film formed in an effective pixel peripheral region, the effective pixel peripheral region being provided so as to enclose an outer side of an effective pixel region in which a plurality of pixels is disposed in a matrix, so as to cover a semiconductor substrate, a microlens layer provided as an upper layer than the first light absorbing film and having a microlens formed so as to condense light for each of the pixels in the effective pixel region, and a second light absorbing film provided as an upper layer than the microlens layer and formed in the effective pixel peripheral region. The present technology can be applied, for example, to a CMOS image sensor.
