On-pitch vias for semiconductor devices and associated devices and systems

Abstract:

Semiconductor devices with on-pitch vias, and associated systems and methods, are disclosed herein. In one embodiment, the semiconductor device may include a 3-dimensional (3D) cross-point memory array. The semiconductor device also includes access lines for the memory array, which couple with on-pitch vias connected to CMOS circuitry disposed underneath the memory array. In some embodiments, a first access line may be coupled with a first via outside a boundary of the memory array, where the first via is separated from the boundary by a first distance and has a first length longitudinal to the first access line. Further, a second access line may be coupled with a second via outside the boundary, where the second via is separated from the boundary by a second distance greater than the first distance and has a second length longitudinal to the second access line, the second length different from the first length.
