Abstract:
A method of forming a memory cell, e.g., flash memory cell, may include (a) depositing polysilicon over a substrate, (b) depositing a mask over the polysilicon, (c) etching an opening in the mask to expose a surface of the polysilicon, (d) growing a floating gate oxide at the exposed polysilicon surface, (e) depositing additional oxide above the floating gate oxide, such that the floating gate oxide and additional oxide collectively define an oxide cap, (f) removing mask material adjacent the oxide cap, (g) etching away portions of the polysilicon uncovered by the oxide cap, wherein a remaining portion of the polysilicon defines a floating gate, and (h) depositing a spacer layer over the oxide cap and floating gate. The spacer layer may includes a shielding region aligned over at least one upwardly-pointing tip region of the floating gate, which helps protect such tip region(s) from a subsequent source implant process.

Claim (Index 17):
A memory cell structure, comprising:\n a floating gate formed over a substrate; and an oxide cap formed over the floating gate, the oxide cap having a smaller lateral width than the underlying floating gate such that a vertically-extending sidewall of the oxide cap is offset from a vertically-extending sidewall of the underlying floating gate in a direction toward a center of the floating gate.
