纳米金属多层膜材料已成为目前高性能微元器件以及互连结构的核心材料体系,其服役过程中的变形损伤与断裂是导致系统失效的关键因素.以本课题组近年来的研究结果为基础,结合当前国内外有关金属多层膜微柱体塑性变形行为研究的最新进展,阐述了金属多层膜微柱体微观结构-尺寸约束-服役性能三者之间的关联性,揭示了金属多层膜微柱体变形模式与损伤的内在规律,归纳了晶体/晶体与晶体/非晶两类层状结构材料加工硬化/软化行为的微观机理,并对纳米金属多层膜研究的发展趋势进行了展望.
Nano-metal multilayer film material has become the core material system of high-performance micro-devices and interconnection structure, and the deformation damage and fracture during service are the key factors that lead to the system failure.Taking the recent research results of this research group as Based on the latest research progress on the plastic deformation behavior of metal multilayer microcapsules at home and abroad, the relationship between the microstructure of the metal multilayer film microstructure - size constraint - service performance is described, and the metal The micro-mechanism of the work-hardening / softening behavior of two kinds of layered structure materials, which are crystal / crystal and crystal / amorphous, was summarized and the development trend of nano-metal multilayer was also discussed Prospects.
