    Abstract: A prober head to interface an E-testing apparatus to a device under test, which may be an unpackaged die, for example. In some embodiments, the prober head includes an array of conductive pins, each of the pins extending outwardly from a first pin end anchored to a substrate. At least a partial length of each of the pins is coated with a hydrophobic monolayer. The conductive pins may be composite metal wires including a core metal encased by one or more peripheral metal. At a tip of the pins, opposite the first pin end anchored to the substrate, the peripheral metals are recessed from the core metal. In further embodiments, the hydrophobic monolayer is disposed on an outer surface of the peripheral metals, but is substantially absent from a surface of the core metal exposed at the tip.

    Abstract: Some example forms relate to a stiffener tape for a wafer. The stiffener tape includes a mounting tape and a stiffener removably attached to the mounting tape. The stiffener tape further includes a die attach film attached to the stiffener. Other example forms relate to an electronic assembly that includes a wafer and a stiffener tape attached to the wafer. The stiffener tape includes a die attach film mounted to the wafer. A stiffener is attached to the die attach film and a mounting tape is removably attached to the stiffener. Still other example forms relate to a method that includes forming a stiffener tape which includes a mounting tape, a stiffener removably attached to the mounting tape and a die attach film attached to the stiffener.

    Abstract: A z-disaggregated integrated circuit package substrate assembly comprises a first substrate component (a coreless patch), a second substrate component (a core patch), and a third substrate component (an interposer). The coreless patch comprises thinner dielectric layers and higher density routing and can comprise an embedded bridge to allow for communication between integrated circuit dies attached to the coreless patch. The core layer acts as a middle layer interconnect between the coreless patch and the interposer and comprises liquid metal interconnects to connect the core patch physically and electrically to the coreless patch and the interposer. Core patch through holes comprise liquid metal plugs. Some through holes can be surrounded by and coaxially aligned with magnetic plugs to provide improved power signal delivery. The interposer comprises thicker dielectric layers and lower density routing. The substrate assembly can reduce cost and provide improved overall yield and electrical performance relative to monolithic substrates.
