Abstract
A method of eliminating interconnect strains in a stack-up is provided. The method includes providing a detector portion including a detector substrate and detector layers, providing a read-out integrated circuit (ROIC) stack-up including ROIC layers and an initial ROIC substrate, removing the initial ROIC substrate from the ROIC layers, attaching a new ROIC substrate to a first surface of the ROIC layers, the new ROIC substrate having a coefficient of thermal expansion (CTE) that matches a CTE of the detector substrate and hybridizing the detector layers to a second surface of the ROIC layers by way of interconnects.
