Abstract: Methods of forming flash memory cells are described which incorporate air gaps for improved performance. The methods are useful for so-called “2-d flat cell” flash architectures. 2-d flat cell flash memory involves a reactive ion etch to dig trenches into multi-layers containing high work function and other metal layers. The methods described herein remove the metal oxide debris from the sidewalls of the multi-layer trench and then, without breaking vacuum, selectively remove shallow trench isolation (STI) oxidation which become the air gaps. Both the metal oxide removal and the STI oxidation removal are carried out in the same mainframe with highly selective etch processes using remotely excited fluorine plasma effluents.

Abstract: Methods of forming air gaps in a 3-d flash memory cell using only gas-phase etching techniques are described. The methods include selectively gas-phase etching tungsten deposited into the stack structure to separate the tungsten levels. Other metals than tungsten may be used. The methods also include selectively etching silicon oxide from between the tungsten levels to make room for vertically spaced air gaps. A nonconformal silicon oxide layer is then deposited to trap the air gaps. Both tungsten removal and silicon oxide removal use remotely excited fluorine-containing apparatuses attached to the same mainframe to facilitate performing both operations without an intervening atmospheric exposure. The nonconformal silicon oxide may be deposited inside or outside the mainframe.
