In this dissertation , a special shape cylindrical target of ybco is designed and sintered for the inverted cylindrical dc sputtering ( icds ) device . then , the thickness distribution of the 3 inch size thin films has been simulated 本文針對3英寸ybco高溫超導雙面薄膜的制備技術,研究了靶材燒制、薄膜膜厚分布、加熱器設計與制作,制備出了具有87k超導性的3英寸ybco雙面薄膜樣品。
Contrasting the results of simulation and the experiment for depositing the 3 inch thin films by icds technique , the center position of substrate and the target is in a 18mm offset , the thickness distribution homogeneity is under 8 % . based on the analyses of the theoretic heat distribution for the radiant heating system , a 3 inch size radiant heater fitting for the requirement is designed and made , whose temperature difference is under 6 % 其次,對3英寸范圍內的膜厚分布進行了理論模擬,在此基礎上和試驗結果對比分析,發現:在倒筒靶直流濺射裝置下,如果采用一種讓基片中心和靶中心處于相對偏心距離為18mm的位置來制備3英寸薄膜,其膜厚分布的均勻度范圍控制在8以內。
The purpose of this dissertation is to study the effect of substrate on the characteristics and microstructure of high temperature superconducting yba2cu3o7 - thin film , and well c - axis oriented epitaxial ybco thin films have been deposited on both laalo3 ( 100 ) and r - plane sapphire al2o3 ( 102 ) substrates by inverted cylindrical dc sputtering ( icds ) technique <中文摘要> =本論文的目的是研究基片對薄膜結構和性能的影響關系,采用倒筒靶直流濺射技術在在laalo3 ( 100 )和r -平面的藍寶石( al2o3 ( 102 ) )兩種基片上制備出c軸取向的外延高溫超導yba2cu3o7 -薄膜。
