Abstract(in English) | Gallium-doped germanium (Ge:Ga) extrinsic semiconductors have been used as sensitive far-infrared detectors with a cutoff wavelength of 110μm (3 THz), especially in the fields of astronomy, the spectroscopy of molecules and solids, and plasma diagnostics. Developing Ge:Ga photoconductor arrays to take two-dimensional THz images is now an important target for such research fields as the space astronomy. We are developing Ge:Ga far-infrared photoconductor direct hybrid arrays for use as focal-plane detectors in the Far Infrared Surveyor (FIS), one of the two main instruments of the Infrared Imaging Surveyor (IRIS) satelite that will be launched in 2003. In this paper, we report on the basic idea of a 20×3 Ge:Ga far-infrared photoconductor array directly hybridized to a Si p-MOS readbut integrated circuit (IC) using indium bump technology, and give the results of vibration and cooling tests conducted to confirm the strength of the direct hybrid structure. |
