Abstract:
Various embodiments of the present application are directed to an integrated circuit (IC) comprising a memory cell with a large operation window and a high erase speed. In some embodiments, the IC comprises a semiconductor substrate and a memory cell. The memory cell comprises a control gate electrode, a select gate electrode, a charge trapping layer, and a common source/drain region. The common source/drain is defined by the semiconductor substrate and is n-type. The control gate electrode and the select gate electrode overlie the semiconductor substrate and are respectively on opposite sides of the common source/drain. Further, the control gate electrode overlies the charge trapping layer and comprises a metal with a p-type work function. In some embodiments, the select gate electrode comprises a metal with an n-type work function.

Claim (Index 17):
The method according to  claim 11 , wherein the semiconductor substrate comprises a memory semiconductor region and a peripheral semiconductor region, wherein the sacrificial control and select gates are formed on the memory semiconductor region, wherein the method further comprises:\n forming a gate dielectric layer covering the memory semiconductor region and the peripheral semiconductor region, wherein the sacrificial gate layer is formed covering the peripheral and memory semiconductor regions over the gate dielectric layer, and wherein the patterning further forms a sacrificial gate on the peripheral semiconductor region; and replacing the sacrificial gate with a gate electrode, wherein the gate electrode comprises a metal with a work function of the first or second doping type, and wherein the replacing removes the gate dielectric layer from the peripheral semiconductor region.
