Finfet gate oxide breakdown
Basis for a FinFET is a lightly p-doped substrate with a hard mask on top (e.g. silicon nitride) as well as a patterned resist layer. See more The fins are formed in a highly anisotropic etch process. Since there is no stop layer on a bulk wafer as it is in SOI, the etch process has to be time based. In a 22 nm process the width of the fins might be 10 to 15 nm, the height … See more To isolate the fins from each other a oxide deposition with a high aspect ratio filling behavior is needed. See more Finally a highly n+-doped poly silicon layer is deposited on top of the fins, thus up to three gates are wrapped around the channel: one on each side of the fin, and - depending on the … See more On top of the fins the gate oxide is deposited via thermal oxidation to isolate the channel from the gate elctrode. Since the fins are still … See more
