    Abstract: Embodiments of a method for device fabrication by reverse pitch reduction flow include forming a first pattern of features above a substrate and forming a second pattern of pitch-multiplied spacers subsequent to forming the first pattern of features. In embodiments of the invention the first pattern of features may be formed by photolithography and the second pattern of pitch-multiplied spacers may be formed by pitch multiplication. Other methods for device fabrication are provided.

    Abstract: The present disclosure includes memory having a continuous channel, and methods of processing the same. A number of embodiments include forming a vertical stack having memory cells connected in series between a source select gate and a drain select gate, wherein forming the vertical stack includes forming a continuous channel for the source select gate, the memory cells, and the drain select gate, and removing a portion of the continuous channel for the drain select gate such that the continuous channel is thinner for the drain select gate than for the memory cells and the source select gate.

    Abstract: Some embodiments include an integrated structure having a first opening extending through a stack of alternating insulative levels and conductive levels. A nitride structure is within the first opening and narrows the first opening to form a second opening. Detectable oxide is between the nitride structure and one or more of the conductive levels. Some embodiments include an integrated structure having a conductive material, a select device gate material over the conductive material, and vertically-stacked conductive levels over the select device gate material. A first opening extends through the vertically-stacked levels to the conductive material and has opposing sidewalls along a cross-section. Nitride liners are along the sidewalls of the first opening. Detectable oxide is between at least one of the nitride liners and one or more of the vertically-stacked conductive levels. Some embodiments include methods for forming integrated structures.
