摘要


本研究利用電漿化學氣相沉積法(Plasma Enhance Chemial Vapor Deposition, PECVD)製備多層二氧化矽封裝薄膜,使用四甲基二矽氧烷(TMSO)輸送至混合槽並與氧氣(O2)做混合產生反應之後通導入腔體內,並藉由調變電漿功率、四甲基二矽氧烷及與氧氣含量來探討其參數之改變對薄膜結構、性質以及OLED效率與壽命的影響,薄膜分析以SEM、UV-visible、FTIR、AFM、色彩分析儀PR-650、LifeTime等儀器量測。 研究結果顯示,在製程溫度25oC製程壓力100mTorr電漿功率300W及TMSO流量200sccm下,沉積出疏水性薄膜,水滴接觸角為105.45o,量測AFM其表面粗糙度(Ra)為3.139nm;接著改變製程參數,電漿功率為400W,TMSO為25sccm及氧氣80sccm,可以沉積出親水性之薄膜,水滴角為2.83o,量測AFM其表面粗糙度(Ra)為0.445nm。 最後利用兩種親水性疏水性不同薄膜的性質,互相搭配沉積單層或多層二氧化矽封裝薄膜,可有效的延長OLED 壽命。

In this study, plasma chemical vapor deposition (Plasma Enhance Chemial Vapor Deposition, PECVD) multilayer thin films of silica encapsulation , using a Tetramethyldisiloxane (TMSO) delivered to the body cavity with oxygen (O2) do mix after the cavity through import react , and by modulating plasma power , four- dimethyl siloxane and oxygen content and to investigate the effect of changing the parameters of the film structure , properties, and OLED efficiency and lifetime of film analysis by SEM, UV-visible, FTIR, AFM, color analyzer PR-650, LifeTime instruments such measurements. The results show that the process temperature is 25oC,plasma process pressure 100mTorr , plasma power 300W and the flow rate 200sccm TMSO , the film can be deposited hydrophobic , water contact angle was measured 105.45o, AFM displayed surface roughness (Ra) of 3.139nm; then change the process parameters , plasma power of 400W, TMSO to 25sccm and oxygen 80sccm, the film can be deposited hydrophilic , the water droplets angle 2.83o, AFM show its surface roughness (Ra) of 0.445nm. Finally, using the properties of two different hydrophilic hydrophobic films , each with a single-layer or multi-layer deposition of silica encapsulation films can effectively extend the life of OLED .
