    Abstract: A reconfigurable optic probe is used to measure signals from a device under test. The reconfigurable optic probe is positioned at a target probe location within a cell of the device under test. The cell including a target net to be measured and non-target nets. A test pattern is applied to the cell and a laser probe (LP) waveform is obtained in response. A target net waveform is extracted from the LP waveform by: i) configuring the reconfigurable optic probe to produce a ring-shaped beam having a relatively low-intensity region central to the ring-shaped beam; (ii) re-applying the test pattern to the cell at the target probe location with the relatively low-intensity region applied to the target net and obtaining a cross-talk LP waveform in response; (iii) normalizing the cross-talk LP waveform; and (iv) determining a target net waveform by subtracting the normalized cross-talk LP waveform from the LP waveform.

    Abstract: The patent application refers to a system and method to test components, circuits and complex equipment, used in order to determine the effect of an external particle flux and of radiation, with different energies, upon the characteristics and operating parameters and, if applicable, upon the program which controls the operation of components, circuits and complex equipment located on-board satellites, space ships or planes flying at high altitudes, that may be part of control systems for nuclear reactors or particle accelerators, intended for handling nuclear materials or waste, or used in areas exposed to nuclear accidents. We suggest a method to generate two or more pulsed fluxes of particles, that can eventually be associated with the emission of gamma or X ray radiation, characterized by specific space configurations, with an aim to use them to perform radiation hardening tests on components and complex systems (intended to operate in outer space or in very demanding environments such as nuclear plants or particle accelerators). According to the patent application, the system is made out of at least two separate laser- plasma particle accelerators (3, 4), placed in different locations with respect to the subsystem (1) under test, fixed on the holder system (2) which is able to rotate and translate, horizontally and vertically, so that the incident particle fluxes (5 and 6) can be applied under different optical angles and to different areas of the subsystem (1). Depending on their design, the laser-plasma accelerators (3 and 4) generate at least two pulsed fluxes of accelerated particles (5 and 6) that may contain identical or different types of particles, by applying incident laser pulses (9 and 10) delivered by two separate high power lasers (7 and 8). The laser beam (9) generated by the high power laser (7) is guided by a mirror (11) towards a parabolic mirror (13) that focuses the beam at the input of a laser-plasma accelerator (3). The laser beam (10) delivered by the high power laser (8), is guided by a mirror (12) towards a parabolic mirror (14), that focuses the beam at the input of another laser-plasma accelerator (4). According to the patent application, the method consists of a calibration procedure and the determination of the operating parameters of the subsystem (1) under test, i) in absence of particle fluxes (5 and 6), ii) in presence of particle fluxes (5 and 6), and iii) after applying the particle fluxes (5 and 6) to the subsystem (1).

    Abstract: A pulsed-laser LADA system is provided, which utilizes temporal resolution to enhance spatial resolution. The system is capable of resolving CMOS pairs within the illumination spot using synchronization of laser pulses with the DUT clock. The system can be implemented using laser wavelength having photon energy above the silicon bandgap so as to perform single- photon LADA or wavelength having photon energy below the silicon bandgap so as to generate two-photon LADA. The timing of the laser pulses can be adjusted using two feedback loops tied to the clock signal of an ATE, or by adjusting the ATE's clock signal with reference to a fixed- pulse laser source.

    Abstract: A method is disclosed for optically inspecting an integrated circuit (IC) comprising a plurality of semiconductor devices (20) on a first surface of a substrate (10) through a lens (310, 410) in or on an area (40) of a further surface of the substrate (10) opposite the first surface. The method comprises a first step of reducing the thickness of the area (40) such that the area, at least when equipped with the lens (310, 410), has an increased transmittance for light having a predefined wavelength, preferably light having a wavelength in the range of 450-700 nm. In a next step, the lens (310, 410) is placed in or on said area (40). The lens may be formed in said area, or may be a separate lens placed on said area. Finally, a subset of the plurality of semiconductor devices (20) is inspected through the lens (310, 410). The method of the present invention has the advantage that, because of the relationship between optical resolution and light wavelength, a better resolution can be obtained when inspecting the IC.
