An understanding of the sputtering process is important for a knowledgeable operation of the FIB. When a Ga + ion is accelerated toward the target sample, it enters the sample and creates a cascade of events which results in the ejection of a sputtered particle (which may be an ion or a neutral atom). This sputtering mechanism thus also results in …
