Abstract

To meet the demands for high temperature-cycling reliability of HgCdTe detectors, bonded to a Silicon 'Read-Out-Integrated- Circuit,' AIM has developed a Multi-Chip-Module approach for the infrared Focal-Plane-Array. Bonding of detector array and Si-chips on a sapphire substrate minimizes thermal stress and strain in the FPA, leading to cycle-to-failure of >= 1000. For maximum cycle estimation under varying strain, a correlation was established empirically.
