  • Publication number: 20230288355
    Abstract: A measurement system and method are presented for measuring one or more parameters of a sample. The measurement system comprises an excitation system and a detection system. The excitation system is configured to generate combined exciting radiation comprising one- or multi-parameter modulation of multiple exciting signals of different types to be applied to at least a portion of a sample under measurements to thereby induce electron emission response of said at least portion of the sample to said combined exciting radiation. The detection system is configured for detecting the electron emission response of the at least portion of the sample and generating measured data indicative of a modulated change of an electrical state of the at least portion of the sample, thereby enabling determination of one or more parameters of the sample from the measured data.

  • Publication number: 20230243766
    Abstract: A measurement system includes: an excitation system; a detector; and a control unit. The excitation system includes excitation sources generating excitations of different types comprising: a high energy electromagnetic radiation source; at least one electric power supply providing a bias voltage to a sample; and at least one electron beam source generating relatively low energy e-radiation in the form of an electron beam. The excitation system includes first and second sequentially performed measurement modes, for respectively, exciting the sample by the high energy radiation to induce a first-mode secondary electron emission spectral response, and supplying initial bias voltage to the sample and exciting the sample with the e-radiation followed by a gradual variation of the bias voltage from said initial bias voltage to induce a second-mode electric current variations in the sample.

  • Patent number: 8507853
    Abstract: The present invention relates to a novel system and method for the determination of depth profiling with improved accuracy and reliability. The method comprises obtaining spectroscopic data from the sample while under at least two different electrical conditions of the sample, the spectroscopic data comprising a signal of charged particles emitted from the sample, and being indicative of a change in amplitude, spectral position and spectral shape of the signal from the sample while under different electrical conditions of the sample, the change being indicative of the compositional profile and spatial distribution for at least one chemical element in the sample along a direction through the sample.

  • Patent number: 7148478
    Abstract: A method and device are presented for measuring the electrical properties of a specimen. The specimen is excited with high energy radiation to cause emission of internal charged particles from the specimen. Electrical power is supplied to a circuit, that is formed by the specimen and any added component connected to a back contact of the specimen. The electric power supply includes at least one of the following: irradiating the circuit with low energy charged particles; subjecting the circuit to an external field of the kind affecting the flux of emitted internal charged particles, and supplying a bias voltage to the back contact of the specimen. During the power supply to the specimen, at least one of the following is carried out: an electric current through the specimen is measured, and the emitted charged particles are analyzed versus their energy (using a contactless voltmeter) which provides local potential values at chemical entities of the specimen.
