Improvements in silicon CCD sensitivity in the NIR by using thick, high resistivity epitaxy silicon, backside illumination, and antireflection (AR) coatings are discussed. Quantum efficiencies at 900 nm of up to 42% for frontside illuminated devices and 78% backside illuminated and AR coated devices are reported.
