Abstract

A new oxygen sensor with PN junction of silicon as the substrate is fabricated.The operation principle

structure design

process and characteristics analysis of the sensor are described.Ag electrodes and TiO

thin films are prepared by RF magnetron sputtering process.The microstructure and surface morphology are examined by X-ray diffractometer（XRD） and scanning electron microscopy（SEM）

and the oxygen-sensitive mechanism of TiO

thin films is discussed.Experiments results show that this kind of sensor has the characteristic of small volume

low power and good linear degreed.
