Abstract: An electron-beam test probe system (400) in which a pulsed laser-beam source (404) and a photocathode assembly (430) are used with an electron-beam column (426) to produce a pulsed electron beam at a stabilized repetition frequency. A pulse picker (414) allows the pulse repetition frequency of the pulsed electron beam to be reduced to a submultiple of the pulsed laser repetition frequency. A test pattern generator (416) is programmable to apply a desired pattern of test vector patterns to an electronic circuit to be probed, the test vector patterns being synchronized with the stabilized laser-beam pulse repetition frequency. A timebase circuit (412) allows the test vector patterns to be time-shifted relative to the pulsed electron beam. The electronic circuit under test can thus be probed at any desired point in the applied test vector pattern by control of the pulse picker and by time-shifting the test vector pattern.

Abstract: A magnetic lens for use in an electron beam test probe system which includes an electron beam which travels along an electron beam column axis to reach the surface of a specimen which is to be examined. The magnetic lens focuses the electron beam to a selected point on the surface of the specimen. This magnetic lens also collects and collimates the secondary electrons produced in response to the electron beam bombardment of the specimen. The magnetic lens includes deflection coils for selecting the point on the specimen surface at which the electron beam is focused. The magnetic lens generates a magnetic field having a first region of intense magnetic flux substantially coincident with the selected point on the specimen surface and a second region of lesser uniform magnetic flux in which the magnetic flux lines are parallel to the electron beam column axis. This field is generated by the combination of a stationary magnetic field and a deflection magnetic field. The stationary magnetic field is modified by the deflection magnetic field which shifts the effective axis of the magnetic lens from the position of the electron beam column axis to a position which intersects the specimen at said selected point. The deflection magnetic field also results in the region of maximum magnetic flux being shifted to said point on the surface.

Abstract: A system and method for controlling electron exposure on image specimens by adjusting a raster scan area in-between scan frame cycles. A small, zoomed-in, scan area and the surrounding area are flooded with positive charge for a number of frame cycles between scan frames to reduce the voltage differential between the scan area and surrounding area, thereby reducing the positive charge buildup which tends to obscure small features in scanned images. The peak current into a pixel element on the specimen is reduced by scanning the beam with a line period that is very short compared to regular video. Frames of image data may further be acquired non-sequentially, in arbitrarily programmable patterns. Alternatively, an inert gas can be injected into the scanning electron microscope at the point where the electron beam impinges the specimen to neutralize a charge build-up on the specimen by the ionization of the inert gas by the electron beam.
