Abstract:
A Wien filter for use in charged particle beam systems is disclosed, having two opposed resistive magnetic pole pieces (106, 108) separated from a set of excitation coils by an electrically insulating material. Two opposed electric pole pieces (114, 116) are positioned in orthogonal relationship to and in physical contact with the magnetic pole pieces to form a physical aperture through which the charged particles will pass. The resistivity of the magnetic pole pieces is such that sufficient current will flow through them between the electric pole pieces to establish a uniform electric field over the entire physical aperture.

Abstract:
An electron energy loss spectrometer for electron microscopy is disclosed having an electrically isolated drift tube extending through the bending magnet and through subsequent optics that focus and magnify the spectrum. An electrostatic or magnetic lens is located either before or after or both before and after the drift tube and the lens or lenses are adjusted as a function of the bending magnet drift tube voltage to maintain a constant net focal length and to avoid defocusing. An energy selecting slit is included in certain embodiments to cleanly cut off electrons dispersed outside the energy range incident on the detector, thereby eliminating artifacts caused by unwanted electrons scattering back into the spectrum.
Abstract:
An implantation system (100) includes an ion extraction plate (106) having a set of apertures configured to extract ions from an ion source (102) to form a plurality of beamlets (112). A magnetic analyzer (114) is configured to provide a magnetic field to deflect ions in the beamlets in a first direction x that is generally perpendicular to a principal axis zof the beamlets. A mass analysis plate (120) includes a set of apertures (122) wherein first ion species (118) having a first mass/charge ratio are transmitted through the mass analysis plate and second ion species (116) having a second mass/charge ratio are blocked by the mass analysis plate. Optionally, a workpiece holder (130) is configured to move with, respect to the mass analysis plate in a second direction y perpendicular to the first direction, wherein a pattern of ions (112a) transmitted through the mass analysis plate forms a continuous ion beam current along the first direction at the substrate (132).
