Abstract: The present invention is generally directed to a method of forming contacts for a memory device. In one illustrative embodiment, the method includes forming a layer of insulating material above an active area of a dual bit memory cell, forming a hard mask layer above the layer of insulating material, the hard mask layer having an original thickness, performing at least two partial etching processes on the hard mask layer to thereby define a patterned hard mask layer above the layer of insulating material, wherein each of the partial etching processes is designed to etch through less than the original thickness of the hard mask layer, the hard mask layer having openings formed therein that correspond to a digitline contact and a plurality of storage node contacts for the dual bit memory cell, and performing at least one etching process to form openings in the layer of insulating material for the digitline contact and the plurality of storage node contacts using the patterned hard mask layer as an etch mask.

Abstract: A method of forming capacitors includes providing a support material over a substrate. The support material is at least one of semiconductive or conductive. Openings are formed into the support material. The openings include at least one of semiconductive or conductive sidewalls. An insulator is deposited along the semiconductive and/or conductive opening sidewalls. A pair of capacitor electrodes having capacitor dielectric there-between is formed within the respective openings laterally inward of the deposited insulator. One of the pair of capacitor electrodes within the respective openings is laterally adjacent the deposited insulator. Other aspects are disclosed, including integrated circuitry independent of method of manufacture.

Abstract: An array includes a plurality of vertically-oriented transistors, rows of access lines, and columns of data/sense lines. Individual of the rows include an access line interconnecting transistors in that row. Individual of the columns include an inner data/sense line elevationally inward of the access lines and which interconnect transistors in that column. An outer data/sense line is elevationally outward of the access lines and electrically couples to the inner data/sense line. Other embodiments are disclosed, including memory arrays and memory cells.

Abstract: Some embodiments include methods in which photolithographically-patterned photoresist features are used as templates during formation of a series of annular structures. The annular structures have linear segments. The linear segments are within a pattern having a pitch which is less than or equal to about half of a pitch of a pattern containing the photoresist features. An expanse of photoresist is formed across the annular structures. The expanse is photolithographically patterned to form chop patterns over ends of the annular structures, and to form at least one opening over at least one of the linear segments. The annular structures are etched while using the patterned photoresist expanse as a mask. In some embodiments, an opening in a photoresist expanse aligns to an edge of a linear segment through scum generated during photolithographic patterning of the photoresist expanse.
