Abstract:This study analyzes the effects of the punch-through stop (PTS) layer and well depth in a bulk FinFET SRAM cell on the fraction of charge generated by an ion impact that is collected by the FinFET channel. More than 1700 3D TCAD simulations have been performed to obtain a detailed map of the sensitivity areas in a full cell 6-T SRAM 22 nm bulk-FinFET process. The influence of the well depth on the charge collected by the drain devices of the SRAM cell has been studied, and it has been concluded that the collec… Show more
