YANG Zi-jian, WEI Bo, WANG Jing-song, et al. Research on preparation process of polyimide capacitive humidity sensor[J]. 2009, 28(4): 56-58. DOI: 10.13873/j.1000-97872009.04.028.
A new structure of the capacitive polyimide humidity sensor which is compatible with standard CMOS technology is prepared.The process is confirmed
and the layout is designed.The parameters of the humidity sensor such as range of measurement and response time are measured.Theoretical simulation is made and compared with the experimental results.The problems and solutions in the experiment are given.
