Title: Manufacture of semiconductor integrated circuit
Inventor: KATSAP VICTOR
IPC: H01J37/06
Filed: 2000-05-08
Abstract: PROBLEM TO BE SOLVED: To improve efficiency and uniformity of an electron beam source in a SCALPEL system by reverse-biasing Wehnelt electrodes of a Wehnelt gun and providing tapered aperture. SOLUTION: The improved Wehnelt electron gun is different from the standard SCALPEL Wehnelt in such a way that the Wehnelt 37 is positively biased with a range of bias voltage between 2000-8000 V. It is reverse-bias compared to the standard SCALPEL Wehnelt. As a result, output beam 41 of laminar flow having almost parallel electron flux lines can be obtained. Namely, few or no crossover exists in the electron beam pattern. In order to improve beam characteristics from the reverse-bias Wehnelt, computer simulation shows that it is preferable that the Wehnelt aperture 38 is tapered.
