WebMay 21, 2024 · These defects occur at the bevel region, if the etched material is exposed at the bevel during the etch process. In floating gate OPOP (Oxide-Poly Si-Oxide-Poly Si) gate first integration, the memory hole etch is non-selective to substrate and severe micromasking at the bevel region can occur during the memory hole and slit etch.

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.
