NVM memory HKMG integration technology
The present disclosure relates to a method of forming an integrated circuit (IC). In some embodiments, a substrate is provided comprising a memory region and a logic region disposed adjacent to the memory region. The memory region comprises a non-volatile memory (NVM) device having a control gate electrode and a select gate electrode disposed between two neighboring source/drain regions over a substrate. The control gate electrode and the select gate electrode comprise polysilicon. The logic region comprises a logic device including a metal gate electrode disposed between two neighboring source/drain regions over a logic gate dielectric and having bottom and sidewall surfaces covered by a high-k gate dielectric layer.
