Claim:
1. A method of manufacturing a substrate-removed, surface passivated, and anti-reflective coated detector assembly, the method comprising: providing a substrate-detector assembly having an imaging detector connected to a substrate; removing a part of the substrate to obtain a partially-removed-substrate detector assembly; etching a backside of the partially-removed-substrate detector assembly to obtain an imaging detector assembly removed from the substrate; depositing, in a vacuum chamber, a wide bandgap layer on the imaging detector assembly; and depositing, in the vacuum chamber, an anti-reflective or passivation coating layer on the wide bandgap layer such that the wide bandgap layer is integrated with the anti-reflective or passivation coating layer and positioned proximal to an interface portion between the anti-reflective or passivation coating layer and the imaging detector assembly.
