ABSTRACT:
A nonvolatile memory cell comprising a pair of spaced apart shallow trench isolation regions formed in a substrate and defining a substrate active region. A tunnel dielectric is formed on the substrate active region. A floating gate is formed on the tunnel dielectric and is self aligned between the spaced apart shallow trench isolation regions. A dielectric layer is formed on the floating gate and a control gate formed on the dielectric layer. A source region and a drain region are formed in the substrate active region on opposite sides of the floating gate.
