Semiconductor constructions and memory arrays
Some embodiments include semiconductor constructions having an electrically conductive interconnect with an upper surface, and having an electrically conductive structure over the interconnect. The structure includes a horizontal first portion along the upper surface and a non-horizontal second portion joined to the first portion at a corner. The second portion has an upper edge. The upper edge is offset relative to the upper surface of the interconnect so that the upper edge is not directly over said upper surface. Some embodiments include memory arrays.
1. A memory array, comprising:
a plurality of electrically conductive interconnects having upper surfaces, the interconnects being spaced from one another by alternating large and small gaps along a cross-section;
angled plate structures over the interconnects; the angled plate structures having horizontal first portions joining to second portions; each angled plate structure having only one horizontal first portion, only one second portion, and only one corner where the horizontal first portion joins to the second portion; the horizontal first portions comprising regions along upper surfaces of the interconnects, the second portions having upper edges that are offset relative to the upper surfaces of the interconnects so that the upper edges are not directly over the upper surfaces; wherein the upper edges are spaced from one another by third gaps along the cross-section, the third gaps being intermediate in dimension relative to the large and small gaps along the cross-section; and
memory material over the upper edges of the angled plate structures.
2. The memory array of claim 1 wherein the third gaps are all of consistent dimension relative to one another.
