    Abstract: Methods of etching back shallow trench isolation (STI) dielectric and trimming the exposed floating gate without breaking vacuum are described. The methods include recessing silicon oxide dielectric gapfill to expose vertical sidewalls of polysilicon floating gates. The exposed vertical sidewalls are then isotropically etched to evenly thin the polysilicon floating gates on the same substrate processing mainframe. Both recessing silicon oxide and isotropically etching polysilicon use remotely excited fluorine-containing apparatuses attached to the same mainframe to facilitate performing both operations without an intervening atmospheric exposure. An inter-poly dielectric may then be conformally deposited either on the same mainframe or outside the mainframe.

    Abstract: An exemplary system may include a chamber configured to contain a semiconductor substrate in a processing region of the chamber. The system may include a first remote plasma unit fluidly coupled with a first access of the chamber and configured to deliver a first precursor into the chamber through the first access. The system may still further include a second remote plasma unit fluidly coupled with a second access of the chamber and configured to deliver a second precursor into the chamber through the second access. The first and second access may be fluidly coupled with a mixing region of the chamber that is separate from and fluidly coupled with the processing region of the chamber. The mixing region may be configured to allow the first and second precursors to interact with each other externally from the processing region of the chamber.

    Abstract: Methods of conformally depositing silicon oxide layers on patterned substrates are described. The patterned substrates are plasma treated such that subsequently deposited silicon oxide layers may deposit uniformly on walls of deep closed trenches. The technique is particularly useful for through-substrate vias (TSVs) which require especially deep trenches. The trenches may be closed at the bottom and deep to enable through-substrate vias (TSVs) by later removing a portion of the backside substrate (near to the closed end of the trench). The conformal silicon oxide layer thickness on the sidewalls near the bottom of a trench is greater than or about 70% of the conformal silicon oxide layer thickness near the top of the trench in embodiments of the invention. The improved uniformity of the silicon oxide layer enables a subsequently deposited conducting plug to be thicker and offer less electrical resistance.
