    Abstract: A dual magnetron particularly useful for RF plasma sputtering includes a radially stationary open-loop magnetron comprising opposed magnetic poles and rotating about a central axis to scan an outer region of a sputter target and a radially movable open-loop magnetron comprising opposed magnetic poles and rotating together with the stationary magnetron. During processing, the movable magnetron is radially positioned in the outer region with an open end abutting an open end of the stationary magnetron to form a single open-loop magnetron. During cleaning, part of the movable magnetron is moved radially inwardly to scan and clean an inner region of the target not scanned by the stationary magnetron. The movable magnetron can be mounted on an arm pivoting about an axis at periphery of a rotating disk-shaped plate mounting the stationary magnetron so the arm centrifugally moves between radial positions dependent upon the rotation rate or direction.

    Abstract: Exemplary semiconductor processing methods may include providing a substrate to a processing region of a semiconductor processing chamber. The substrate may include an alternating stack of materials. A feature may extend through the alternating stack of materials. One material of the alternating stack of materials may include a silicon-containing material. A native oxide material may be disposed on at least a portion of exposed surfaces of the silicon-containing material. The methods may include performing a pre-clean treatment on the substrate. The methods may include providing a fluorine-containing precursor to the processing region. The methods may include contacting the substrate with the fluorine-containing precursor, wherein the contacting removes native oxide from the silicon-containing material.
