Abstract:
The present disclosure relates to a structure and method for embedding a non-volatile memory (NVM) in a HKMG (high-κ metal gate) integrated circuit which includes a high-voltage (HV) HKMG transistor. NVM devices (e.g., flash memory) are operated at high voltages for its read and write operations and hence a HV device is necessary for integrated circuits involving non-volatile embedded memory and HKMG logic circuits. Forming a HV HKMG circuit along with the HKMG periphery circuit reduces the need for additional boundaries between the HV transistor and rest of the periphery circuit. This method further helps reduce divot issue and reduce cell size.

Claim (Index 9):
An integrated circuit (IC) comprising:\n a semiconductor substrate including a memory cell region and a peripheral region, wherein a boundary region that includes an isolation structure separates the memory cell region from the peripheral region; a pair of split gate flash memory cells, which comprises a pair of select gates and a pair of individual source/drain regions on opposite outermost sides of the pair of select gates, disposed over the memory cell region, wherein the pair of individual source/drain regions includes a first individual source/drain region nearest the isolation structure, and wherein the first individual source/drain region is spaced apart from the isolation structure by a portion of the semiconductor substrate; a first transistor, which comprises a first gate electrode, disposed over the peripheral region; and a second transistor, which comprises a second gate electrode that is thicker than the first gate electrode, disposed over the peripheral region; and wherein upper surfaces of the pair of select gates are co-planar or level with an upper surface of the first gate electrode, and are co-planar or level with an upper surface of the second gate electrode.
