摘要
采用反应溅射法制备了ITO透明导电薄膜材料,薄膜电阻率为2.59×10-4Ω·cm,可见光透过率可达90%;通过优化光刻工艺条件,选择合适的ITO薄膜刻蚀液,完成了ITO透明栅电极的制作;使用ITO透明电极代替其中一相多晶硅电极,制作的CCD图像传感器,其蓝光响应明显增加。
Transparent conductive indium-tin-oxide(ITO)films were deposited by reactive sputtering.The conductance and the maximal transmittance of the films are obtained to be 2.59×10^-4 Ω·cm and greater than 90% for the visible light spectrum,respectively.By optimizing the lithography process and using the appropriate ITO etching fluid,the ITO transparent gate electrodes were successfully fabricated,and CCD image sensors were fabricated by replacing one of the CCD's polysilicon electrodes with ITO.The blueresponse of the sensors is significantly improved.
