Abstract : The preparation technologies and the capacitance humidity sensitive characters of anodic oxidation porous Al2O3 thin film have been investigated. The humidity response characters had been analyzed with the af2 fection of anodic oxidation parameters on the structure and morphology of porous Al2O3 thin film ,as a high quali2 ty humidity response material of humidity sensor. So it could put forth more sufficient experiment datum to im2
prove the processing parameters and made this new porous Al2O3 thin film humidity sensor with more splendid humidity response properties.
Key words : porous Al2O3 thin film; humidity sensor ; anodic oxidation
