摘要
The process parameters are adjusted and the process procedure is simplified on the basis of precursor's work and the strained Si channel SiGe n MOSFET is fabricated successfully.This n MOSFET takes the strained Si layer(which is deposited on the relaxed SiGe buffer layer) as current channel and can provide a 48 5% improvement in electron mobility while keeping the gate voltage as 1V.
通过参数调整和工艺简化 ,制备了应变Si沟道的SiGeNMOS晶体管 .该器件利用弛豫SiGe缓冲层上的应变Si层作为导电沟道 ,相比于体Si器件在 1V栅压下电子迁移率最大可提高 48 5 % .
