氧化鉭薄膜的制備及光學(xué)性能研究
摘要
如今光學(xué)薄膜已經(jīng)被廣泛研究并應(yīng)用于光纖通信、航空航天以及軍事等諸多領(lǐng)域，如光學(xué)集成電路與光學(xué)微機(jī)械電子系統(tǒng)、表面光學(xué)處理模塊與器件等作為動(dòng)態(tài)隨機(jī)存儲(chǔ)(DRAM)、金屬氧化硅晶體管、減反膜、高溫阻抗、氣敏傳感器、以及電容器的關(guān)鍵材料等。Ta2O5薄膜具有很多優(yōu)良的光學(xué)性能，如在可見光范圍有較大折射率(n=2.2 at 633 nm)、較小的消光系數(shù)，是一種性能優(yōu)異的光學(xué)薄膜，具有很好的應(yīng)用前景。
本實(shí)驗(yàn)以氧化鉭為靶材，以氧和氬的混合氣體為濺射氣體，采用磁控濺射法在三個(gè)不同的濺射功率下制備了三組氧化鉭薄膜樣品。重點(diǎn)研究了不同的濺射功率對(duì)薄膜的沉積速率、折射率及透光率的影響。
采用光譜橢偏儀研究了濺射功率對(duì)氧化鉭薄膜沉積速率、折射率和光學(xué)帶隙的影響，結(jié)果表明隨著濺射功率的增大，薄膜的沉積速率提高，薄膜的折射率增大，但對(duì)光學(xué)帶隙無明顯的影響。采用紫外-可見分光光度計(jì)對(duì)氧化鉭薄膜的透過率進(jìn)行了分析，結(jié)果顯示氧化鉭薄膜對(duì)300~2000 nm波段的光波的透光率接近90%，且隨著濺射功率的提高，薄膜的透光率降低。

The study of tantalum oxide thin films and its optical properties
Abstract
Optical film has been extensively studied and applied to the optical fiber communication, aerospace and military, and many other fields, such as optical integrated circuits and optical micro-mechanical and electronic systems, surface optical processing module and device, as a key material used in dynamic randomaccess memory (DRAM), metal oxide silicon transistor, anti-reflection film, high temperature resistance, gas sensors, and capacitors. Ta2O5 film having excellent optical properties, such as in the visible range and a larger refractive index (n = 2.2 at 633 nm), the extinction coefficient is small, so it is a high performance of an optical film and have a good application prospect.
Tantalum oxide films were prepared under three different sputtering power by magnetron sputtering on glass substrates from tantalum oxide target in a mixed gas of oxygen and argon. Influence of the sputtering power on deposition rate, refractive index and light transmittance of the films was investigated.
Thickness, refractive index and optical bandgap of the tantalum oxide films with different sputtering power were analyzed by spectroscopic ellipsometry deposition. The results show that with increasing sputtering power, the deposition rate increases, and the refractive index of the film increases, but the optical bandgap has no significant change. The transmittance of tantalum oxide thin film was determined by ultraviolet-visible spectrophotometer. The results show that the transmittance of tantalum oxide film in the wavelength of 300 ~ 2000 nm is close to 90%, and with the sputtering power increasing, the transmittance of the thin film decreases due to an decrease of the film density.
