Ion Source
Plasma ion source, LMIS, and GFIS are three common types of ion sources. LMIS and GFIS have excellent source brightness. Therefore they are widely used in high-resolution ion beam imaging and micromachining applications. However, the total current from LMIS and GFIS is many orders of magnitude lower than plasma ion sources. If the feature size is larger than 50nm, the plasma ion source can achieve a much higher throughput than LMIS and GFIS.
