High-temperature electronics is needed for geothermal well-logging tools, jet engine monitors, nuclear reactor instruments, and fossil fuel exploration and production systems. The step-by-step fabrication technology of thick-film hybrids useful for at least 1000 hours at 275/sup 0/C is described. Hybrid technology, qualified to standard military specifications, was modified both in materials and fabrication processes to achieve this high-temperature operation. In addition to documenting this Sandia-developed technology, various alternate approaches are described to increase the versatility and applicability of these methods.
