Abstract: 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.

Abstract: Some embodiments include an integrated assembly having a base which includes first circuitry. Memory decks are over the base. Each of the memory decks has a sense/access line coupled with the first circuitry. The memory decks and base are vertically spaced from one another by gaps. The gaps alternate in a vertical direction between first gaps and second gaps. Overlapping conductive paths extend from the sense/access lines to the first circuitry. The conductive paths include first conductive interconnects within the first gaps and second conductive interconnects within the second gaps. The first and second conductive interconnects are laterally offset relative to one another.

Abstract: Methods, systems, and devices for electron beam probing techniques and related structures are described to enable inline testing of memory device structures. Conductive loops may be formed, some of which may be grounded and others of which may be electrically floating in accordance with a predetermined pattern. The loops may be scanned with an electron beam and image analysis techniques may be used to generate an optical pattern. The generated optical pattern may be compared to an expected optical pattern, which may be based on the predetermined pattern of grounded and floating loops. An electrical defect may be determined based on any difference between the generated optical pattern and the expected optical pattern. For example, if a second loop appears as having a brightness corresponding to a grounded loop, this may indicate that an unintended short exists. Fabrication techniques may be adjusted for subsequent devices to correct identified defects.

Abstract: Methods, systems, and devices supporting a socket design for a memory device are described. A die may include one or more memory arrays, which each may include any number of word lines and any number of bit lines. The word lines and the bit lines may be oriented in different directions, and memory cells may be located at the intersections of word lines and bit lines. Sockets may couple the word lines and bit lines to associated drivers, and the sockets may be located such that memory cells farther from a corresponding word line socket are nearer a corresponding bit line socket, and vice versa. For example, sockets may be disposed in rows or regions that are parallel to one another, and which may be non-orthogonal to the corresponding word lines and bit lines.

Abstract: Structures and methods for separating semiconductor wafers into individual dies are disclosed. A semiconductor wafer or panel can include a crack assist structure in a scribe junction. The crack assist structure can include a plurality of vertical walls extending at least partially through a thickness of the wafer. In some embodiments, the plurality of vertical walls can be coupled to a weak interface. The weak interface can guide cracks that form during the dicing process in a direction along the walls, away from active circuitry. After dicing, the resulting semiconductor devices can include a plurality of vertical walls extending at least partially through a thickness of the semiconductor device. Each of the plurality of vertical walls can include at least a portion extending substantially parallel to a sidewall of the semiconductor device.

Abstract: 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 insulative material at least partially over an electrically conductive feature. The method can further include forming a ring of electrically non-conductive material extending at least partially about a sidewall of the insulative material that defines the opening. The method can further include removing a portion of the ring to form an opening over the electrically conductive feature, and then depositing an electrically conductive material into the opening in the ring to form a conductive via electrically coupled to the electrically conductive feature.
