Embodiments of the present technology may include a method for implementing communications between an MC and an NC that involves establishing Internet Protocol (IP) connectivity between the MC and the NC using Network Controller Sideband Interface (NC-SI) control packets and communicating between the MC and the NC via an NC-SI and the established IP connectivity.
Abstract: A row of backside support pillar structures is formed through a first-tier alternating stack of first-tier insulating layers and first-tier sacrificial material layers. At least one upper-tier alternating stack can be formed, and memory stack structures can be formed through the alternating stacks. A backside trench can be formed through the alternating stacks selective to the row of backside support pillar structures. The sacrificial material layers are replaced with electrically conductive layers, and the backside trench can be filled with a backside trench fill structure, which includes the row of backside support pillar structures. The row of backside support pillar structures reduces or prevents tilting or collapse of the alternating stacks during replacement of the sacrificial material layers with the electrically conductive layers.
Abstract: A alternating stack of insulating layers and sacrificial material layers is formed over a substrate. An array of memory opening fill structures and an array of support pillar structures are formed through the alternating stack. Backside trenches are formed through the alternating stack by performing an anisotropic etch process. The anisotropic etch process etches peripheral portions of a subset of the array of support pillar structures. The sacrificial material layers are replaced with electrically conductive layer by forming backside recesses while the support pillar structures provide mechanical support to the insulating layers.
Abstract: A method for mitigating crack propagation during manufacture of semiconductor dies, and associated systems and methods are disclosed herein. The method includes forming holes into a first side of a wafer substrate opposite a second side. The wafer substrate has active components at the second side. Each hole extends from the first side towards the second side an extend to an intermediate depth within the wafer substrate such that a bottom of the holes is spaced vertically apart from the active components on the second side. The holes are configured to inhibit cracks in the wafer substrate from propagating longitudinally across the wafer substrate. The method also includes backgrinding the first side of the wafer substrate to thin the wafer substrate after forming the holes. The method also includes dicing the wafer substrate after backgrinding to separate individual semiconductor dies from each other.

Abstract: A data capturing system for use with aerial spherical imagery is provided. The system allows for capturing and tracking of data with respect to those accessing and viewing particular aerial spherical imagery, such as the imagery on a GIS map. The data capturing system may include a server having a processor and a memory and a software application providing instruction to the server to display aerial spherical imagery, such as spherical imagery, to a user through a network connection, such as through the Internet. For example the system may provide the map as a website to the user that is displayed on a remote computing device accessible by the user in order to view the spherical imagery. Data related to the interaction of the user with the website is captured and tracked in order to use such data for other purposes.
