Study of equipment design for testability and diagnostic strategy optimization

In this paper, a novel atmospheric pressure sensor was researched by using SOl （silicon on insulator） materials and fabricated with double-islands structure. The insulated isolation layer was used to eliminate the PN-junction noise, therefore the performances, such as SNR, linearity, repeatability, etc, were improved. The practical temperature, measured by using the temperature characteristic of the sensitive resistance, was used in temperature compensation to improve the veracity. The experiment data shows that the sensor s precision meets the requirement in meteorology.
