Paper Abstract

Infrared systems for the future include a variety of device configurations. The most studied system is the hybrid focal plane array consisting of a photovoltaic CdHgTe (PV CMT) matrix interconnected by metallic bumps to a CCD silicon chip.CCD devices are more versatile than other silicon circuits, they can be operated in Time, Delay, and Integration mode (TDI) for scanned imaging or in staring mode. But CCD requires high impedance PV detector for direct injection in CCD wells with high coupling efficiency. An other critical performance needed for detectors is low l/f noise for high detectivity at low frequencies. The present work describes recent results obtained on PV CMT detectors and their coupling to CCD circuits.
