Abstract: Techniques and structures are disclosed related to coupling to gate-all-around transistors for test and/or debug of an integrated circuit. The gate-all-around transistors, which may also be referred to as 3D stacked transistors or ribbon-FET transistors are contacted directly from the back side or they are contacted using a dedicated probe point on the back side of the gate-all-around transistors. Such contact may be made to probe the devices and/or to provide edit wires to modify the integrated circuit.

Abstract: An apparatus comprising a beam emitter to emit a beam comprising electrons, ions or laser-light photons toward a target substrate. A motion sensor to detect mechanical vibrations of the target substrate. The motion sensor is mechanically coupled to the target substrate, a processor coupled to an output of the motion sensor. The processor is to generate a vibration correction signal proportional to the mechanical vibrations detected by the motion sensor, and beam steering optics coupled to the processor. The beam steering optics are to deflect the beam according to the vibration correction signal to compensate for the mechanical vibrations of the target substrate.

Abstract: A probe assembly for analyzing a test device that includes a housing with an electron source disposed therein for emitting primary electrons. A photon source is positioned to emit photons that strike the electron source such that when the photons strike the electron source, the electron source emits the primary electrons. Detection circuitry is provided that is configured to detect secondary electrons emitted from a test device of a test assembly and to form an excitation waveform.
