Also, die pad to z-interconnect connectors formed by the methods, and shaped and dimensioned accordingly. Also, stacked die assemblies and stacked die packages containing die prepared according to the methods and having die pad to z-interconnect connectors formed by the methods and shaped and dimensioned accordingly.
Abstract:
Additive processes are employed for electrically insulating selected surface regions on a stack of die; and methods for electrically interconnecting die in a stack of die, include additive processes for electrically insulating selected surface regions of the die. Regions that are not insulated according to the invention are available for electrical connection using electrically conductive material applied in flowable form to make electrically conductive traces.
Abstract:
An interconnect terminal is formed on a semiconductor die by applying an electrically conductive material in an aerosol form, for example by aerosol jet printing. Also, an electrical interconnect between stacked die, or between a die and circuitry in an underlying support such as a package substrate, is formed by applying an electrically conductive material in an aerosol form, in contact with pads on the die or on the die and the substrate, and passing between the respective pads. In some embodiments a fillet is formed at the inside corner formed by an interconnect sidewall of the die and a surface inboard from pads on an underlying feature (underlying die or support); and the electrically conductive material passes over a surface of the fillet.
Abstract:
Exemplary embodiments provide methods and systems for assembling electronic devices, such as integrated circuit (IC) chips, by selectively and seating IC elements onto/into a receiving substrate, such as a chip substrate. Specifically, the assembly of IC chips can include embedding IC elements onto the receiving substrate upon softening the receiving substrate. Such softening can be performed by using a softening agent and/or an activatable thermal barrier material. In an exemplary embodiment, pockets can be formed in the receiving substrate using the activatable thermal barrier material for the IC assembly.
Abstract:
Die vorliegende Erfindung betrifft insbesondere eine Vorrichtung mit einem auf einem Substrat (3) befestigtem elektronischen Bauelement (1), insbesondere einem elektronischen Leistungsbauelement oder Halbleiterleistungsbauelement, wobei auf dem Bauelement (1) und auf dem Substrat (3) eine elektrisch isolierende Isolationsschicht (6) aufgebracht ist. Zur Flächenkontaktierung oberer elektrischer Kontaktflächen (12) des elektronischen Bauelements (1) werden Fenster in der Isolationsschicht (6) geöffnet. Danach erfolgt ein flächiges Kontaktieren der freigelegten oberen elektrischen Kontaktflächen (12). Es ist Aufgabe der vorliegenden Erfindung bei derart flächig kontaktierten elektronischen Bauelementen (1) bei unveränderter Gesamtschichtdicke der verwendeten Isolationsschichten (6), die Isolation zwischen elektrischen Anschlüssen (12, 13) an der Bauelementoberseite und an dessen Unterseite hinsichtlich Spannungssicherheit beziehungsweise Isolationsfestigkeit zu verbessern. Durch eine Verrundung von oberen Kanten (7) des Bauelements (1), mittels einer elektrisch isolierenden Materialaufbringung (5), wird ein Ausdünnen der elektrisch isolierenden Folie (6) im Bereich der mindestens einen oberen Kante (7) beziehungsweise oberen Kanten (7) vermieden. Auf diese Weise kann bei gleicher Dicke der Isolationsschicht (6) eine erhöhte Spannungssicherheit beziehungsweise Isolationsfestigkeit bereitgestellt werden.
