  • Chromium black light shield
    Patent number: 6939015
    Abstract: A black light shield for preventing incident light from being received by light receiving elements, the black shield includes a support structure; a first CrOx layer disposed over the support structure for absorbing the incident light in a substantially reflected transmission path; and a second CrOx layer disposed integral with the support structure for absorbing the incident light in a substantially non-reflected transmission path.
    Type: Grant

  • Image sensor having improved spectral response uniformity
    Patent number: 6489642
    Abstract: An image sensor, includes a semiconductor substrate; a photosensor having, a first photosensing region including a first stack of one or more layers of transparent materials overlying the substrate, the first photosensing region having a spectral response having peaks and valleys, and a second photosensing region including a second stack of one or more layers of transparent materials overlying the substrate, the second photosensing region having a spectral response having peaks and valleys; and wherein at least one peak or valley of the spectral response of the first region is matched to at least one valley or peak respectively of the spectral response of the second region such that the average spectral response of the photosensor is smoother than the individual spectral response of either the first or second photosensing regions.
