Abstract: A silicon nitride barrier layer is deposited on a gallium arsenide substrate to prevent evaporation of the substrate in subsequent heating steps. A silicon dioxide stress reduction layer is deposited on the barrier layer. A first electrode is formed on the stress reduction layer, then a liquid precursor is spun on the first electrode, dried at about 400° C., and annealed at between 600° C. and 850° C. to form a BST capacitor dielectric. A second electrode is deposited on the dielectric and annealed.

Abstract: The value of a variable reflecting the operating condition of mechanical equipment is continuously detected as operation condition data. A long period average value of the operating condition data detected in long reference period, and a short period average value of data detected in a short analysis period ending in the present time are calculated. Just how much the short period average value differs from the long period average value is adopted as an index of abnormality and using this index, it is possible to ascertain abnormal operating conditions regardless of the absolute value of the variable detected. The above short period average value, long period average value and standard deviation thereof are applied to a first fuzzy membership function for calculating the degree of stability of the mechanical equipment therefrom.
