An ion beam is a beam produced by accelerating ions at high speed.

To generate an ion beam for FIB, a liquid metal ion source (LMIS) consisting of a needle-shaped tungsten filament with gallium attached is used. When the filament is heated and voltage is applied to the extraction electrode, an ion beam is generated from the tip. The generated ions are then controlled by the accelerator's electric and magnetic fields to form a narrow, directional stream.

The ion beam generator consists of an ion source (ion gun), an electromagnetic lens in the accelerator, and a deflector. The ion beam passes through an accelerator and is used for ion implantation of impurities into semiconductors, surface cleaning by ion milling, surface processing, surface modification, and surface and internal analysis.

The ion beam is accelerated and decelerated by an electric field in a vacuum, and deflected by a magnetic field. Ion mass sorting is performed by bending the ions in a magnetic field, and energy analysis is performed by decelerating electric field method and electrostatic field deflection analysis method.

Matsusada Precision offers a variety of power supply equipment for ion acceleration, extraction, suppression, deflection, focusing, gridding and neutralization.
