WebTypically, a 45% overetch is used to achieve a 0.07 reduction in linewidth. The wafer is then sequenced to the poly chamber to remove the gate polysilicon. The first step is a breakthrough to remove any residuals and to break any native oxides on the poly. The second step is used to clear the poly to gate oxide, and is run until poly clear is seen. WebBasis 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. 2. Fin etch. 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 ...
WebAfter gate etch there is deposition, there is a poly-Si residue-ring along the field/ a wet polymer strip sequence: a sulfuric acid and hydrogen active area border (also in between two fins).
