Abstract:
In some embodiments, an electronic device processing system is provided that includes a processing tool having a first subsystem configured to carry out a first subset of processes on a substrate having pattern features, the first subsystem including a first conformal deposition chamber and a first etch chamber. The processing tool includes a second subsystem coupled to the first subsystem and configured to carry out a second subset of processes on the substrate, the second subsystem including a second conformal deposition chamber and a second etch chamber. The processing tool is configured to employ the first and second subsystems to perform pitch division on the substrate within the processing tool so as to form a reduced-pitch pattern on the substrate. Numerous other embodiments are provided.
Abstract:
Systems, chambers, and processes are provided for controlling process defects caused by moisture contamination. The systems may provide configurations for chambers to perform multiple operations in a vacuum or controlled environment. The chambers may include configurations to provide additional processing capabilities in combination chamber designs. The methods may provide for the limiting, prevention, and correction of aging defects that may be caused as a result of etching processes performed by system tools.
Abstract:
Methods of etching back an oxide-nitride-oxide (ONO) layer of a 3-d flash memory cell without breaking vacuum are described. The methods include recessing the two outer silicon oxide dielectric layers to expose the flanks of the thin silicon nitride layer. The silicon nitride layer is then etched back from all exposed sides to hasten the process on the same substrate processing mainframe. Both etching back the silicon oxide and etching back the silicon nitride use remotely excited fluorine-containing apparatuses attached to the same mainframe to facilitate performing both operations without an intervening atmospheric exposure. The process may also be reversed such that the silicon nitride is etched back first.

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.
