中文摘要
本論文利用電子束蒸鍍系統鍍製AZO薄膜,分別在不同氧工作壓力及不同基板溫度條件下鍍製薄膜。AZO薄膜特性分別以四點探針、紫外線光譜儀、SEM及AFM量測並對薄膜微結構和光電性質做探討。最後設計多層膜鏡片,並以AZO取代ITO導電薄膜,鍍製抗輻射多層膜鏡片。
鍍製AZO薄膜於氧工作壓1×10-4 Torr、基板溫度80℃下,量測薄膜之電阻係數為9.2×10-4 Ω-cm,波長510nm之折射率為2.05,可見光區域透光度可達到83%以上。
鍍製AZO於多層膜鏡片之研究方面,在腔體壓力5.0×10-5 Torr,離子鎗工作壓力6.0×10-5 Torr、氧流量36 sccm、基板溫度80℃、離子鎗電壓6.2V時,可見光區域鏡片透光率可達94%以上。
Abstract
In this study, the AZO thin films were deposited with various manufacturing conditions, such as working pressure of oxygen and substrate temperature, by e-beam evaporation. The microstructure of the AZO film was observed by SEM and AFM. Sheet resistance was measured using four-point probe method. Optical transmittance was measured in the visible range by UV spectrophotometer. Finally, AZO transparent film was used as a substitute for ITO to fabricate the radiation-resistant glasses.
The optimum parameters for depositing AZO films are glass substrates of 80℃ and working pressure of 1×10-4 Torr. The film resistance is 9.2×10-4 Ω-cm with a film thickness of 60 nm. The refractive index was measured to be 2.05 at a wavelength of 510 nm. The optical transmittance of the prepared films was above 83 % in the visible range.
The manufacturing conditions for depositing AZO multilayer coatings are working pressure of 5.0×10-5 Torr, ion gun working pressure of 6.0×10-5 Torr, voltage of 6.2 V, oxygen gas flow rate of 36 sccm and glass substrates of 80℃. The optical transmittance of the glass was above 94 % in the visible range.
