Methods of manufacturing semiconductor devices, and associated systems and devices, are disclosed herein. In some embodiments, a method of manufacturing a semiconductor device includes forming an opening in an electrically insulative material at least partially over a first electrically conductive feature and a second electrically conductive feature. The method can further include forming a ring of electrically conductive material around a sidewall of the insulative material defining the opening, wherein the ring of electrically conductive material includes (a) a first via portion over the first electrically conductive feature, (b) a second via portion over the second electrically conductive feature, and (c) connecting portions extending between the first and second via portions. Finally, the method can include removing the connecting portions of the ring of electrically conductive material to electrically isolate the first via portion from the second via portion.
