Abstract

High-sensitivity device based on meso-piezoresistive effect of multi-barrier nano films was used to micro-machined gyroscope.The structure of such micro-machined gyroscope was proposed and its operation principle was also discussed.The fabrication processes of this gyroscope were developed and designed.Through the measurement of structure

some deficiencies in the fabrication processes were found

including the mutil-barrier nano film manufacturing defects

the detection beam and drive beam manufacturing defects

the detects of electromagnetic signal interference defects and package defects etc.The problems in manufacturing process were analyzed

the reasons for the formation of defects were summarized and the approaches to solve these problems were proposed.The fabrication processes of resonant tunneling micro-machined gyroscope are improved and the production yield is increased.
