Electron beam lithography system.
HITACHI HL 950 scanning electron microscope (SEM) is a high resolution electron microscope designed for imaging the surface of small samples with nanoscale resolution. It uses a combination of a high-energy electron beam and scanning unit to create images at a magnification of up to 4,500x. The SEM has a wide range of applications in fields such as materials science, microelectronics, chemistry, and biology. HL 950 SEM has a built-in Ø150-280 mm objective lens system capable of magnifying up to 4,500x, making it ideal for micro- and nanoscale imaging. It also has a 0.60 NA infinitely adjustable aberration-corrector lens which can produce high-resolution images without introducing distortion. The SEM is equipped with an electron gun capable of accelerating electrons up to 20 keV with an adjustable beam current of 0.2 - 25 nanomamps. This high voltage allows the SEM to penetrate and survey structures on the micrometer- and nanometer-scale. The SEM has a compact design with a high-resolution monochrome CCD camera connected directly to the rear electron gun for in-focus imaging or, when necessary, a secondary side-mounted camera for off-axis imaging. The software includes automatic stage control, limit detection and correction, and software image processing capabilities like contour and edge detection to improve image clarity. HITACHI HL 950 SEM is also equipped with a high-vacuum chamber to reduce electron-beam induced sample charging effects. The chamber maintains a base pressure of 1 x 10-6 Torr and all the necessary fixtures and components including an EHT power supply and several ion pumps, electron and gas detectors, and a variable cathode voltage. The SEM is compatible with secondary imaging techniques including energy-dispersive X-ray spectroscopy (EDS), electron backscatter diffraction (EBSD), and atom-probe tomography (APT). HITACHI EDS software can detect elements down to trace concentrations, which is a great advantage when analyzing sample composition or quality. Finally, HL 950 SEM has a variety of safety features to minimize chances of damage to both the samples and the operator. An anti-contamination shield is fitted over the sample to reduce the risk of accidental exposure. A door interlock system prevents the SEM from being powered up without the shield in place.
