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.
