Semiconductor devices having redistribution structures, and associated systems and methods, are disclosed herein. In one embodiment, a semiconductor package includes a first semiconductor die including a first redistribution structure and a second semiconductor die including a second redistribution structure. The first and second semiconductor dies can be mounted on a package substrate such that the first and second redistribution structures are aligned with each other. In some embodiments, an interconnect structure can be positioned between the first and second semiconductor dies to electrically couple the first and second redistribution structures to each other. The first and second redistribution structures can be configured such that signal routing between the first and second semiconductor dies can be altered based on the location of the interconnect structure.

Substrates with continuous slot vias are disclosed herein. In one embodiment, a substrate comprises a first design layer, a second design layer, and an intermediary layer between the first and second design layers. The substrate further includes first and second signaling vias extending vertically through the intermediary layer between the first and second design layers. The first and second signaling vias route first and second data signals, respectively, between the first and second design layers. The substrate further includes a slot via that is positioned between the first and second signaling vias within the intermediary layer and extends laterally within the intermediary layer along a path that passes between the first signaling via and the second signaling via. The slot via can have a continuous shape such that the slot via shields the first and second data signals on the first and second signaling vias from crosstalk with one another.

Substrates with continuous slot vias

A semiconductor device has first and second dies forming a die stack. Molding material encapsulates the die stack and forms an upper molded surface of the die stack. First conductive traces are coupled to the first die and extend from between the first and second die to corresponding first via locations in the molding material beyond a first side edge of the die stack. Second conductive traces coupled to an active surface of the second die opposite the first die extend to corresponding second via locations. Each first via location is vertically aligned with one of the second via locations. Through mold vias extend through the molding material between vertically aligned via locations to contact with corresponding conductive traces of the first and second dies, while the molding material that extends between the first conductive traces and the upper molded surface is free from any TMV.

Semiconductor assemblies with system and methods for conveying signals using through mold vias

An apparatus comprising a substrate having conductive traces and associated integral terminal pads on a surface thereof, the terminal pads having an irregular surface topography formed in a thickness of a single material of the conductive traces and integral terminal pads. Solder balls may be bonded to the terminal pads, and one or more microelectronic components operably coupled to conductive traces of the substrate on a side thereof opposite the terminal pads. Methods of fabricating terminal pads on a substrate, and electronic systems including substrates having such terminal pads are also disclosed.

Systems and methods for releasing semiconductor dies during pick and place operations are disclosed. In one embodiment, a system for handling semiconductor dies comprises a support member positioned to carry at least one semiconductor die releasably attached to a support substrate. The system further includes a picking device having a pick head coupleable to a vacuum source and positioned to releasably attach to the semiconductor die at a pick station. The system still further incudes a cooling member coupleable to a cold fluid source and configured to direct a cold fluid supplied by the cold fluid source toward the support substrate at the pick station. The cold fluid cools a die attach region of the substrate where the semiconductor die is attached to the substrate to facilitate removal of the semiconductor die.
