초록
This paper presents a capacitive humidity sensor using porous silicon layers formed tom the anodization of p-type silicon in HF solution. The upper electrodes consist of many aluminum strips over porous silicon, between which the porous silicon is etched away. The sensor showed a good sensitivity(20pF/%RH) and lineaity in the range of 40%RH
