摘要
研究了退火态 Cr- Si- Al和 Cr- Si- Al- Zr薄膜的微观结构和电性能 .结果表明 ,溅射态非晶薄膜 Cr- Si- Al和 Cr- Si- Al- Zr在加热到 70 0°C的过程中 ,主要析出 2种晶化相 :Cr(Al,Si) 2 和 Si纳米晶化相 ,其中 Cr- Si- Al- Zr薄膜中的晶化相 Cr(Al,Si) 2 包含有少量 Zr原子 .Zr原子的加入抑制了晶化相的形核和长大 ,从而 Cr- Si- Al- Zr薄膜与 Cr- Si- Al薄膜相比 ,需更高的退火温度才能达到趋于零的电阻温度系数 .因此 ,Cr- Si- Al- Zr薄膜具有更好的电学稳定性能 .
The microstructure and electrical properties of annealed Cr-Si-Al and Cr-Si-Al-Zr films were investigated. When sputtered amorphous Cr-Si-Al and Cr-Si-Al-Zr films were heated up to 700°C, both of them were found to crystallize into two phases: the nanocrystalline Cr(Al,Si)2 and Si phase. For Cr-Si-Al-Zr films, zirconium atoms were also found to be dissolved in the crystallization phase Cr(Al,Si)2 in small amounts. The addition of Zr into amorphous Cr-Si-Al films inhibited the nucleation and growth of the crystallization phase, resulting in the higher annealing temperatures for Cr-Si-Al-Zr films in comparison with Cr-Si-Al films to obtain a small temperature coefficient of resistance. As a result, the Cr-Si-Al-Zr films have higher electrical stability.
