Abstract:
A memory cell, e.g., a flash memory cell, includes a substrate, a flat-topped floating gate formed over the substrate, and a flat-topped oxide region formed over the flat-topped floating gate. The flat-topped floating gate may have a sidewall with a generally concave shape that defines an acute angle at a top corner of the floating gate, which may improve a program or erase efficiency of the memory cell. The flat-topped floating gate and overlying oxide region may be formed with without a floating gate thermal oxidation that forms a conventional “football oxide.” A word line and a separate erase gate may be formed over the floating gate and oxide region. The erase gate may overlap the floating gate by a substantially greater distance than the word line overlaps the floating gate, which may allow the program and erase coupling to the floating gate to be optimized independently.

Claim (Index 19):
The flash memory cell of  claim 16 , further comprising a word line and a separate erase gate formed over the floating gate.
