Besides,electromigration is also a serious issue for the reliability of devices . There are two principle methods of reducing the RC delay. The first method is to replace the Al wires with Cu interconnects which supply lower resistivity and high resistance to electromigration. The second method is to use a lower dielectric constant material as the inter-metal dielectric. But in Copper metallization,the key issue of this technology is the formation of a thin barrier layer for Cu on the surface of the SiC film to prevent the absorption of water and diffusion of Cu. In this study,we employed films SiC base compounds to investigate their chemical bonds, I-V characteristics comparisons with Al and Cu gate. On the other hand, because of serious C-V hysteretic phenomena, we try to analyze and build up models. There five models is reasonable for our experiment: (1) mobile ions, (2) dielectric polarization, (3) carrier injection, (4) gate-electrons injection, and (5) bound charges. They happens in different materials and structures. Ting-Chang Chang 張鼎張 2002 學位論文 ; thesis 60 en_US |
