Abstract
Fabrication of avalanche photodiodes on a first wafer for operation in Geiger mode and integration with read-out integrated circuits (ROICs), fabricated on a second wafer, are described. Photodiode arrays are fabricated using a thin epitaxial layer grown on a semiconductor-on-insulator wafer. Chips are diced from the first wafer and bump bonded to chips diced from the second wafer.
