Abstract:
The present disclosure relates to a method of forming an embedded flash memory cell that provides for improved performance by providing for a tunnel dielectric layer having a relatively uniform thickness, and an associated apparatus. The method is performed by forming a charge trapping dielectric structure over a logic region, a control gate region, and a select gate region within a substrate. A first charge trapping dielectric etching process is performed to form an opening in the charge trapping dielectric structure over the logic region, and a thermal gate dielectric layer is formed within the opening. A second charge trapping dielectric etching process is performed to remove the charge trapping dielectric structure over the select gate region. Gate electrodes are formed over the thermal gate dielectric layer and the charge trapping dielectric structure remaining after the second charge trapping dielectric etching process.

Claim (Index 12):
The integrated chip of  claim 8 , further comprising:\n an isolation structure disposed along opposite sides of the second channel region to laterally confine the second channel region to the channel width, wherein the tunnel dielectric layer has a first thickness over a peripheral region of the second channel region nearer the isolation structure and has a second thickness over a central region of the second channel region further from the isolation structure, the second thickness being less than the first thickness.
