WebThe etcher is also equipped with a 2-zone gas showerhead providing radial distribution control of the neutral species. Etch data were taken for 4 poly-gate steps: fluorocarbon-based BARC etching, fluorocarbon TEOS hard mask open, fluorocarbon-based high-dope poly etching and HBr-based poly etching.
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. how do i set my pc to start scanning canonWebMar 16, 2015 · Its over etch is more aggressive than conventional planar gate to avoid poly-si residue.
