Zusammenfassung:A miniature electron beam column in combination with magnetostatic lenses to produce very high-performance miniature electron or ion beam columns. Silicon-based electron optical components provide high-accuracy formation and alignment of critical optical elements and the magnetic lenses provide low-aberration focusing or condensing elements. Accurate assembly of the silicon and magnetic components is achievable via the multilayered assembly techniques and allows for achieving high performance.
