利用电子能量损失谱研究了Si(100)/SiO2/HfO 2/TiN/poly-Si栅叠层中的界面反应。核心边缘上的电子能量损失近边缘精细结构显示出TiN金属栅极和周围层之间发生界面反应的证据。在TiN/poly-Si界面处观察到Si(O,N)相。(c)2006年,美国物理学会。
Interface reactions are investigated in a Si(100)/SiO2/HfO2/TiN/poly-Si gate stack using electron-energy-loss spectroscopy. The electron-energy-loss near-edge fine structure on the core edges shows evidence of interface reactions having occurred between the TiN metal gate and surrounding layers. A Si(O,N) phase is observed at the TiN/poly-Si interface. (c) 2006 American Institute of Physics.
