国际商业机械公司发展了通过快速冷却过程的激光退火.想法很简单:只要使用激光射线的特性,就能把一定材料的区域加热至高温.突然冷却能使高温获得的改变结构保持不变. 激光技术为改变薄膜特性提供了一种非常灵敏的工具.例如,我们能在准确的温度下加热一个样品.在这一温度下能看到晶体结构的变化.冷却 International Business Machines Corporation developed laser annealing by a rapid cooling process. The idea is simple: just use the characteristics of a laser beam to heat a region of a given material up to a high temperature. Sudden cooling keeps the changing structure that is obtained at a high temperature. Technology provides a very sensitive tool for changing thin film properties, for example, by heating a sample at the exact temperature at which crystal structure changes can be seen.
