Abstract:
1. An all solid-state, monolithic, back-illuminated, semiconductor wafer substrate apparatus for transmitting ultraviolet, visible and near infrared radiation into the semiconductor layer with efficiency approaching 100%, comprising: a silicon (Si) or silicon-germanium (SiGe) semiconductor layer, wherein said silicon (Si) or silicon-germanium (SiGe) semiconductor layer comprises light detector elements (pixels) for imaging focal plane arrays, detecting radiation in the ultraviolet, visible and near infrared; and a sapphire dielectric layer for providing mechanical support to said silicon (Si) or silicon-germanium (SiGe) semiconductor layer, and also transmitting ultraviolet, visible and near infrared radiation; and an antireflective bilayer wherein said antireflective bilayer comprises a single crystal aluminum nitride (AlN) antireflective layer and also a non-stoichiometric, silicon rich, amorphous silicon nitride (a-SiN a single one quarter wavelength thick, amorphous magnesium fluoride (MgF
