Abstract:
A method of forming a semiconductor structure includes forming a sacrificial material over a stack comprising alternating levels of a dielectric material and another material, forming an opening through the sacrificial material and at least some of the alternating levels of the dielectric material and the another material, forming at least one oxide material in the opening and overlying surfaces of the sacrificial material, an uppermost surface of the at least one oxide material extending more distal from a surface of a substrate than an uppermost level of the dielectric material and the another material, planarizing at least a portion of the at least one oxide material to expose a portion of the sacrificial material, and removing the sacrificial material while the uppermost surface of the at least one oxide material remains more distal from the surface of the substrate than the uppermost level of the alternating levels of the dielectric material and the another material. Related methods of forming semiconductor structures and related semiconductor devices are disclosed.
Abstract:
Some embodiments include semiconductor constructions having first and second electrically conductive lines that intersect with one another at an intersection. The first line has primarily a first width, and has narrowed regions directly against the second line and on opposing sides of the second line from one another. Electrically conductive contacts are along the first line and directly electrically coupled to the first line, and one of the electrically conductive contacts is directly against the intersection. Some embodiments include methods of forming intersecting lines of material. First and second trenches are formed, and intersect with one another at an intersection. The first trench has primarily a first width, and has narrowed regions directly against the second trench and on opposing sides of the second trench from one another. Material is deposited within the first and second trenches to substantially entirely fill the first and second trenches.

Abstract:
A semiconductor device in accordance with some embodiments includes a substrate structure and a conductive interconnect extending through at least a portion of the substrate structure. The conductive interconnect can include a through-silicon via and a stress-relief feature that accommodates thermal expansion and/or thermal contraction of material to manage internal stresses in the semiconductor device. Methods of manufacturing the semiconductor device in accordance with some embodiments includes removing material of the conductive interconnect to form the stress-relief gap.
