  • Publication number: 20250231233
    Abstract: A socket of a testing tool is configured to provide testing signals. A device-under-test (DUT) board is configured to provide electrical routing. An integrated circuit (IC) die is disposed between the socket and the DUT board. The testing signals are electrically routed to the IC die through the DUT board. The IC die includes a substrate in which plurality of transistors is formed. A first structure contains a plurality of first metallization components. A second structure contains a plurality of second metallization components. The first structure is disposed over a first side of the substrate. The second structure is disposed over a second side of the substrate opposite the first side. A trench extends through the DUT board and extends partially into the IC die from the second side. A signal detection tool is configured to detect electrical or optical signals generated by the IC die.

  • Publication number: 20250185171
    Abstract: An integrated circuit (IC) chip assembly includes an integrated circuit (IC) die that includes a first substrate in which plurality of transistors is formed, a first structure that contains a plurality of first metallization components, and a second structure that contains a plurality of second metallization components. The first structure is disposed over a first side of the first substrate. The second structure is disposed over a second side of the first substrate opposite the first side. The chip assembly includes a second substrate bonded to the IC die through the second side. The chip assembly includes a trench that extends through the second substrate and through the second structure of the IC die. Sidewalls of the trench are defined at least in part by one or more protective layers.

  • Publication number: 20240038587
    Abstract: A semiconductor substrate includes a plurality of transistors. A first structure is disposed over a first side of the semiconductor substrate. The first structure contains a plurality of first metallization components. A carrier substrate is disposed over the first structure. The first structure is located between the carrier substrate and the semiconductor substrate. One or more openings extend through the carrier substrate and expose one or more regions of the first structure to the first side. A second structure is disposed over a second side of the semiconductor substrate opposite the first side. The second structure contains a plurality of second metallization components.
