Abstract :
A self-aligned contact ETOXtrade flash memory process with W-gate capable of MLC operation is presented for the first time. Several key process elements were successfully integrated to achieve functional test structures. Significant cell area reduction can be realized using the SAC architecture by aggressive cell height scaling and thus this approach provides a manufacturable path for continued future scaling of flash memories.
