Abstract: Exemplary methods for removing cobalt material may include flowing a chlorine-containing precursor into a processing region of a semiconductor processing chamber. The methods may include forming a plasma of the chlorine-containing precursor to produce plasma effluents. The methods may also include contacting an exposed region of cobalt with the plasma effluents. The methods may include flowing a nitrogen-containing precursor into the processing region of the semiconductor processing chamber. The methods may further include contacting the cobalt chloride with the nitrogen-containing precursor. The methods may also include recessing the cobalt, which leaves a residue behind. The methods may include forming a remote plasma of a hydrogen-containing precursor. The methods may also include removing the cobalt residue using plasma effluents of the hydrogen-containing precursor.
Abstract: Aspects of the disclosure include methods of treating a substrate to remove one or more of voids, seams, and grain boundaries from interconnects formed on the substrate.

Abstract: Methods of forming 3-d flash memory cells are described. The methods allow the cells to be produced despite a misalignment in at least two sections (top and bottom), each having multiple charge storage locations. The methods include selectively gas-phase etching dielectric from the bottom memory hole portion by delivering the etchants through the top memory hole. The methods further include placing sacrificial polysilicon around the memory hole before forming the bottom stack and removing the sacrificial polysilicon from the slit trench to allow a conducting gapfill to make electrical contact to the polysilicon inside the memory hole.

The methods allow the cells to be produced despite a misalignment in at least two sections (top and bottom), each having multiple charge storage locations. The methods include selectively gas-phase etching dielectric from the bottom memory hole portion by delivering the etchants through the top memory hole. Two options for completing the methods include (1) forming a ledge spacer to allow reactive ion etching of the bottom polysilicon portion without damaging polysilicon or charge-trap/ONO layer on the ledge, and (2) placing sacrificial silicon oxide gapfill in the bottom memory hole, selectively forming protective conformal silicon nitride elsewhere, then removing the sacrificial silicon oxide gapfill before performing the reactive ion etching of the bottom polysilicon portion as before.

A remote plasma may be formed from a fluorine-containing precursor to produce plasma effluents. The methods may include flowing the plasma effluents to the processing region of the semiconductor processing chamber. The methods may also include removing the modified oxidized silicon from the semiconductor substrate. The methods may include isotropically etching a silicon-containing material from the semiconductor substrate.
