Electrode assembly, electronic apparatus/device using the same, and apparatus of charged-particle beam such as electron microscope using the same
The present invention provides an electrode assembly comprising two or more electrodes arranged around a primary axis forming a non-cylindrical channel space. General electronic apparatus/device, particularly apparatus of charged-particle beam such as electron microscope, may use the electrode assembly to create an optimized pattern of electrical field within non-cylindrical channel space. When the electrode assembly is used as a beam deflector in a magnetic objective lens, the electrical field within the central channel space can be co-optimized with the magnetic field for reducing aberration(s) such as distortion, field curvature, astigmatism, and chromatic aberration, after the beam passes through the central channel space.
Electron microscope stage
A positioning system for an electron microscope includes a first carriage comprising a holder for holding a workpiece and a second carriage. The first carriage being coupled to one or more first drive units configured to position the workpiece along first, second, and third axes, and along a first tilt axis. The second carriage housing the one or more first drive units and being coupled to one or more second drive units configured to position the workpiece along a second tilt axis.
Digital detector, apparatus of charged-particle beam such as electron microscope comprising the same, and method thereof
The present invention provides a digital high-resolution detector for detecting X-ray, UV light or charged particles.
