Abstract:
1. A wafer-integration uncooled infrared (IR) microbolometer focal plane array (FPA) sensor device comprising: at least a first layer comprising at least one FPA of uncooled IR microbolometers, said at least a first layer comprises at least a portion of a read out integrated circuit (ROIC); at least a second layer comprising a least one signal processing circuit, said at least a second layer comprises at least a portion of an ROIC; wherein said at least a first layer and said at least a second layer are aligned and interconnected; and wherein separate optimized manufacturing processes are used for each of said at least a first layer and said at least a second layer, whereby additional processing cost of said at least a first layer is leveraged, minimizing total device cost and maximizing die count per wafer.
