WebDuring ion beam etching processes, the chamber pressure typically reaches values between 2.5 and 6E-4 Torr. This means that the ion beam is highly directional being in an essentially collisionless environment with a mean free path > 20 cm, greater than the distance between source and substrate. WebA schematic of the ion beam system is shown in Fig. 1. The dc Kaufman- type ion beam source was fitted with graphite grids of 150 mm diameter. The ion beam was …

WebIf 4 grids are utilised, the ion extraction and acceleration processes can be separated, permitting total potentials of up to at least 80 kV to be employed. This concept has been proved in an experimental programme at ESTEC, for which several special diagnostic instruments were designed and built to characterise the high energy ion beam. Web9 mei 2024 · H. R. Kaufman, Applications of Broad-Beam Ion Sources: An Introduction (Kaufmann Robinson, Inc., 2011). Ions are extracted from a plasma source by a set of electrically biased grids. The voltage applied to these grids controls the ion energy and the divergence of the ions within the beam.
