Novel body tied FinFET cell array transistor DRAM with negative word line operation for sub 60nm technology and beyond
In this paper, a highly manufacturable 512M FinFET DRAM with novel body tied FinFET cell array transistor on bulk Si substrate has been successfully integrated and the characteristics were compared with RCAT (Recess Channel Array Transistor) and planar cell array transistor DRAM for the first time. We also propose the NWL (Negative Word Line) scheme with low channel doping body tied FinFET for a highly manufacturable FinFET DRAM for sub 60nm technology node.
