项目摘要
In order to investigate the plastic deformation mechanism in nano-components where a nano-thickness copper(Cu) film is sandwiched between a silicon(Si) substrate and silicon nitride(SiN) layer, we developed a bending specimen, of which understructure can be observed in-situ by means of a transmission electron microscope(TEM), and examined the plastic behavior of a Cu portion. TEM images exhibited that an initial plastic deformation took place near the interface edge(junction between the Cu/Si interface and the surface) in the Cu portion with a high critical resolved shear stress(400. 420 MPa). The TEM observation after the experiment indicated that stacking fault layers governed the plastic deformation in nano-scale region near the dissimilar interface.
为了研究纳米组件中的塑性变形机制,其中将纳米厚度铜(CU)膜夹在硅(SI)底物和氮化硅(SIN)层之间通过透射电子显微镜(TEM)观察到原位,并检查了Cu部分的塑性行为。 TEM图像表明,在CU部分的界面边缘(Cu/Si界面和表面之间的连接)附近发生了初始塑性变形,并具有高临界分辨的剪切应力(400。420MPA)。实验后的TEM观察结果表明,堆叠断层层控制着不同界面附近纳米尺度区域的塑性变形。
